+.SH "NAME"
+os-release, initrd-release, extension-release \- Operating system identification
+.SH "SYNOPSIS"
+.PP
+/etc/os\-release
+.PP
+/usr/lib/os\-release
+.PP
+/etc/initrd\-release
+.PP
+/usr/lib/extension\-release\&.d/extension\-release\&.\fIIMAGE\fR
+.SH "DESCRIPTION"
+.PP
+The
+/etc/os\-release
+and
+/usr/lib/os\-release
+files contain operating system identification data\&.
+.PP
+The format of
+os\-release
+is a newline\-separated list of environment\-like shell\-compatible variable assignments\&. It is possible to source the configuration from Bourne shell scripts, however, beyond mere variable assignments, no shell features are supported (this means variable expansion is explicitly not supported), allowing applications to read the file without implementing a shell compatible execution engine\&. Variable assignment values must be enclosed in double or single quotes if they include spaces, semicolons or other special characters outside of A\(enZ, a\(enz, 0\(en9\&. (Assignments that do not include these special characters may be enclosed in quotes too, but this is optional\&.) Shell special characters ("$", quotes, backslash, backtick) must be escaped with backslashes, following shell style\&. All strings should be in UTF\-8 encoding, and non\-printable characters should not be used\&. Concatenation of multiple individually quoted strings is not supported\&. Lines beginning with "#" are treated as comments\&. Blank lines are permitted and ignored\&.
+.PP
+The file
+/etc/os\-release
+takes precedence over
+/usr/lib/os\-release\&. Applications should check for the former, and exclusively use its data if it exists, and only fall back to
+/usr/lib/os\-release
+if it is missing\&. Applications should not read data from both files at the same time\&.
+/usr/lib/os\-release
+is the recommended place to store OS release information as part of vendor trees\&.
+/etc/os\-release
+should be a relative symlink to
+/usr/lib/os\-release, to provide compatibility with applications only looking at
+/etc/\&. A relative symlink instead of an absolute symlink is necessary to avoid breaking the link in a chroot or initrd environment such as dracut\&.
+.PP
+os\-release
+contains data that is defined by the operating system vendor and should generally not be changed by the administrator\&.
+.PP
+As this file only encodes names and identifiers it should not be localized\&.
+.PP
+The
+/etc/os\-release
+and
+/usr/lib/os\-release
+files might be symlinks to other files, but it is important that the file is available from earliest boot on, and hence must be located on the root file system\&.
+.PP
+os\-release
+must not contain repeating keys\&. Nevertheless, readers should pick the entries later in the file in case of repeats, similarly to how a shell sourcing the file would\&. A reader may warn about repeating entries\&.
+.PP
+For a longer rationale for
+os\-release
+please refer to the
+\m[blue]\fBAnnouncement of /etc/os\-release\fR\m[]\&\s-2\u[1]\d\s+2\&.
+.SS "/etc/initrd\-release"
+.PP
+In the
+\m[blue]\fBinitrd\fR\m[]\&\s-2\u[2]\d\s+2,
+/etc/initrd\-release
+plays the same role as
+os\-release
+in the main system\&. Additionally, the presence of that file means that the system is in the initrd phase\&.
+/etc/os\-release
+should be symlinked to
+/etc/initrd\-release
+(or vice versa), so programs that only look for
+/etc/os\-release
+(as described above) work correctly\&.
+.PP
+The rest of this document that talks about
+os\-release
+should be understood to apply to
+initrd\-release
+too\&.
+.SS "/usr/lib/extension\-release\&.d/extension\-release\&.\fIIMAGE\fR"
+.PP
+/usr/lib/extension\-release\&.d/extension\-release\&.\fIIMAGE\fR
+plays the same role for extension images as
+os\-release
+for the main system, and follows the syntax and rules as described in the
+\m[blue]\fBPortable Services\fR\m[]\&\s-2\u[3]\d\s+2
+page\&. The purpose of this file is to identify the extension and to allow the operating system to verify that the extension image matches the base OS\&. This is typically implemented by checking that the
+\fIID=\fR
+options match, and either
+\fISYSEXT_LEVEL=\fR
+exists and matches too, or if it is not present,
+\fIVERSION_ID=\fR
+exists and matches\&. This ensures ABI/API compatibility between the layers and prevents merging of an incompatible image in an overlay\&.
+.PP
+In order to identify the extension image itself, the same fields defined below can be added to the
+extension\-release
+file with a
+\fISYSEXT_\fR
+prefix (to disambiguate from fields used to match on the base image)\&. E\&.g\&.:
+\fISYSEXT_ID=myext\fR,
+\fISYSEXT_VERSION_ID=1\&.2\&.3\fR\&.
+.PP
+In the
+extension\-release\&.\fIIMAGE\fR
+filename, the
+\fIIMAGE\fR
+part must exactly match the file name of the containing image with the suffix removed\&. In case it is not possible to guarantee that an image file name is stable and doesn\*(Aqt change between the build and the deployment phases, it is possible to relax this check: if exactly one file whose name matches
+"extension\-release\&.*"
+is present in this directory, and the file is tagged with a
+\fIuser\&.extension\-release\&.strict\fR
+\fBxattr\fR(7)
+set to the string
+"0", it will be used instead\&.
+.PP
+The rest of this document that talks about
+os\-release
+should be understood to apply to
+extension\-release
+too\&.
+.SH "OPTIONS"
+.PP
+The following OS identifications parameters may be set using
+os\-release:
+.SS "General information identifying the operating system"
+.PP
+\fINAME=\fR
+.RS 4
+A string identifying the operating system, without a version component, and suitable for presentation to the user\&. If not set, a default of
+"NAME=Linux"
+may be used\&.
+.sp
+Examples:
+"NAME=Fedora",
+"NAME="Debian GNU/Linux""\&.
+.RE
+.PP
+\fIID=\fR
+.RS 4
+A lower\-case string (no spaces or other characters outside of 0\(en9, a\(enz, "\&.", "_" and "\-") identifying the operating system, excluding any version information and suitable for processing by scripts or usage in generated filenames\&. If not set, a default of
+"ID=linux"
+may be used\&. Note that even though this string may not include characters that require shell quoting, quoting may nevertheless be used\&.
+.sp
+Examples:
+"ID=fedora",
+"ID=debian"\&.
+.RE
+.PP
+\fIID_LIKE=\fR
+.RS 4
+A space\-separated list of operating system identifiers in the same syntax as the
+\fIID=\fR
+setting\&. It should list identifiers of operating systems that are closely related to the local operating system in regards to packaging and programming interfaces, for example listing one or more OS identifiers the local OS is a derivative from\&. An OS should generally only list other OS identifiers it itself is a derivative of, and not any OSes that are derived from it, though symmetric relationships are possible\&. Build scripts and similar should check this variable if they need to identify the local operating system and the value of
+\fIID=\fR
+is not recognized\&. Operating systems should be listed in order of how closely the local operating system relates to the listed ones, starting with the closest\&. This field is optional\&.
+.sp
+Examples: for an operating system with
+"ID=centos", an assignment of
+"ID_LIKE="rhel fedora""
+would be appropriate\&. For an operating system with
+"ID=ubuntu", an assignment of
+"ID_LIKE=debian"
+is appropriate\&.
+.RE
+.PP
+\fIPRETTY_NAME=\fR
+.RS 4
+A pretty operating system name in a format suitable for presentation to the user\&. May or may not contain a release code name or OS version of some kind, as suitable\&. If not set, a default of
+"PRETTY_NAME="Linux""
+may be used
+.sp
+Example:
+"PRETTY_NAME="Fedora 17 (Beefy Miracle)""\&.
+.RE
+.PP
+\fICPE_NAME=\fR
+.RS 4
+A CPE name for the operating system, in URI binding syntax, following the
+\m[blue]\fBCommon Platform Enumeration Specification\fR\m[]\&\s-2\u[4]\d\s+2
+as proposed by the NIST\&. This field is optional\&.

+\fIVARIANT=\fR
+.RS 4
+A string identifying a specific variant or edition of the operating system suitable for presentation to the user\&. This field may be used to inform the user that the configuration of this system is subject to a specific divergent set of rules or default configuration settings\&. This field is optional and may not be implemented on all systems\&.
+.sp
+Examples:
+"VARIANT="Server Edition"",
+"VARIANT="Smart Refrigerator Edition""\&.
+.sp
+Note: this field is for display purposes only\&. The
+\fIVARIANT_ID\fR
+field should be used for making programmatic decisions\&.
+.sp
+Added in version 220\&.
+.RE
+.PP
+\fIVARIANT_ID=\fR
+.RS 4
+A lower\-case string (no spaces or other characters outside of 0\(en9, a\(enz, "\&.", "_" and "\-"), identifying a specific variant or edition of the operating system\&. This may be interpreted by other packages in order to determine a divergent default configuration\&. This field is optional and may not be implemented on all systems\&.
+.sp
+Examples:
+"VARIANT_ID=server",
+"VARIANT_ID=embedded"\&.
+.sp
+Added in version 220\&.
+.RE
+.SS "Information about the version of the operating system"
+.PP
+\fIVERSION=\fR
+.RS 4
+A string identifying the operating system version, excluding any OS name information, possibly including a release code name, and suitable for presentation to the user\&. This field is optional\&.
+.sp
+Examples:
+"VERSION=17",
+"VERSION="17 (Beefy Miracle)""\&.
+.RE
+.PP
+\fIVERSION_ID=\fR
+.RS 4
+A lower\-case string (mostly numeric, no spaces or other characters outside of 0\(en9, a\(enz, "\&.", "_" and "\-") identifying the operating system version, excluding any OS name information or release code name, and suitable for processing by scripts or usage in generated filenames\&. This field is optional\&.
+.sp
+Examples:
+"VERSION_ID=17",
+"VERSION_ID=11\&.04"\&.
+.RE
+.PP
+\fIVERSION_CODENAME=\fR
+.RS 4
+A lower\-case string (no spaces or other characters outside of 0\(en9, a\(enz, "\&.", "_" and "\-") identifying the operating system release code name, excluding any OS name information or release version, and suitable for processing by scripts or usage in generated filenames\&. This field is optional and may not be implemented on all systems\&.
+.sp
+Examples:
+"VERSION_CODENAME=buster",
+"VERSION_CODENAME=xenial"\&.
+.sp
+Added in version 231\&.
+.RE
+.PP
+\fIBUILD_ID=\fR
+.RS 4
+A string uniquely identifying the system image originally used as the installation base\&. In most cases,
+\fIVERSION_ID\fR
+or
+\fIIMAGE_ID\fR+\fIIMAGE_VERSION\fR
+are updated when the entire system image is replaced during an update\&.
+\fIBUILD_ID\fR
+may be used in distributions where the original installation image version is important:
+\fIVERSION_ID\fR
+would change during incremental system updates, but
+\fIBUILD_ID\fR
+would not\&. This field is optional\&.
+.sp
+Examples:
+"BUILD_ID="2013\-03\-20\&.3"",
+"BUILD_ID=201303203"\&.
+.sp
+Added in version 200\&.
+.RE
+.PP
+\fIIMAGE_ID=\fR
+.RS 4
+A lower\-case string (no spaces or other characters outside of 0\(en9, a\(enz, "\&.", "_" and "\-"), identifying a specific image of the operating system\&. This is supposed to be used for environments where OS images are prepared, built, shipped and updated as comprehensive, consistent OS images\&. This field is optional and may not be implemented on all systems, in particularly not on those that are not managed via images but put together and updated from individual packages and on the local system\&.
+.sp
+Examples:
+"IMAGE_ID=vendorx\-cashier\-system",
+"IMAGE_ID=netbook\-image"\&.
+.sp
+Added in version 249\&.
+.RE
+.PP
+\fIIMAGE_VERSION=\fR
+.RS 4
+A lower\-case string (mostly numeric, no spaces or other characters outside of 0\(en9, a\(enz, "\&.", "_" and "\-") identifying the OS image version\&. This is supposed to be used together with
+\fIIMAGE_ID\fR
+described above, to discern different versions of the same image\&.
+.sp
+Examples:
+"IMAGE_VERSION=33",
+"IMAGE_VERSION=47\&.1rc1"\&.
+.sp
+Added in version 249\&.
+.RE
+.PP
+To summarize: if the image updates are built and shipped as comprehensive units,
+\fIIMAGE_ID\fR+\fIIMAGE_VERSION\fR
+is the best fit\&. Otherwise, if updates eventually completely replace previously installed contents, as in a typical binary distribution,
+\fIVERSION_ID\fR
+should be used to identify major releases of the operating system\&.
+\fIBUILD_ID\fR
+may be used instead or in addition to
+\fIVERSION_ID\fR
+when the original system image version is important\&.
