+.SH "NAME"
+ukify \- Combine components into a signed Unified Kernel Image for UEFI systems
+.SH "SYNOPSIS"
+.HP \w'\fBukify\fR\ 'u
+\fBukify\fR [OPTIONS...] build
+.HP \w'\fBukify\fR\ 'u
+\fBukify\fR [OPTIONS...] genkey
+.HP \w'\fBukify\fR\ 'u
+\fBukify\fR [OPTIONS...] inspect FILE...
+.SH "DESCRIPTION"
+.PP
+\fBukify\fR
+is a tool whose primary purpose is to combine components (usually a kernel, an initrd, and a UEFI boot stub) to create a
+\m[blue]\fBUnified Kernel Image (UKI)\fR\m[]\&\s-2\u[1]\d\s+2
+\(em a PE binary that can be executed by the firmware to start the embedded linux kernel\&. See
+\fBsystemd-stub\fR(7)
+for details about the stub\&.
+.SH "COMMANDS"
+.PP
+The following commands are understood:
+.SS "build"
+.PP
+This command creates a Unified Kernel Image\&. The two primary options that should be specified for the
+\fBbuild\fR
+verb are
+\fILinux=\fR/\fB\-\-linux=\fR, and
+\fIInitrd=\fR/\fB\-\-initrd=\fR\&.
+\fIInitrd=\fR
+accepts multiple whitespace\-separated paths and
+\fB\-\-initrd=\fR
+can be specified multiple times\&.
+.PP
+Additional sections will be inserted into the UKI, either automatically or only if a specific option is provided\&. See the discussions of
+\fICmdline=\fR/\fB\-\-cmdline=\fR,
+\fIOSRelease=\fR/\fB\-\-os\-release=\fR,
+\fIDeviceTree=\fR/\fB\-\-devicetree=\fR,
+\fISplash=\fR/\fB\-\-splash=\fR,
+\fIPCRPKey=\fR/\fB\-\-pcrpkey=\fR,
+\fIUname=\fR/\fB\-\-uname=\fR,
+\fISBAT=\fR/\fB\-\-sbat=\fR, and
+\fB\-\-section=\fR
+below\&.
+.PP
+\fBukify\fR
+can also be used to assemble a PE binary that is not executable but contains auxiliary data, for example additional kernel command line entries\&.
+.PP
+If PCR signing keys are provided via the
+\fIPCRPrivateKey=\fR/\fB\-\-pcr\-private\-key=\fR
+and
+\fIPCRPublicKey=\fR/\fB\-\-pcr\-public\-key=\fR
+options, PCR values that will be seen after booting with the given kernel, initrd, and other sections, will be calculated, signed, and embedded in the UKI\&.
+\fBsystemd-measure\fR(1)
+is used to perform this calculation and signing\&.
+.PP
+The calculation of PCR values is done for specific boot phase paths\&. Those can be specified with the
+\fIPhases=\fR/\fB\-\-phases=\fR
+option\&. If not specified, the default provided by
+\fBsystemd\-measure\fR
+is used\&. It is also possible to specify the
+\fIPCRPrivateKey=\fR/\fB\-\-pcr\-private\-key=\fR,
+\fIPCRPublicKey=\fR/\fB\-\-pcr\-public\-key=\fR, and
+\fIPhases=\fR/\fB\-\-phases=\fR
+arguments more than once\&. Signatures will then be performed with each of the specified keys\&. On the command line, when both
+\fB\-\-phases=\fR
+and
+\fB\-\-pcr\-private\-key=\fR
+are used, they must be specified the same number of times, and then the n\-th boot phase path set will be signed by the n\-th key\&. This can be used to build different trust policies for different phases of the boot\&. In the config file,
+\fIPCRPrivateKey=\fR,
+\fIPCRPublicKey=\fR, and
+\fIPhases=\fR
+are grouped into separate sections, describing separate boot phases\&.
+.PP
+If a SecureBoot signing key is provided via the
+\fISecureBootPrivateKey=\fR/\fB\-\-secureboot\-private\-key=\fR
+option, the resulting PE binary will be signed as a whole, allowing the resulting UKI to be trusted by SecureBoot\&. Also see the discussion of automatic enrollment in
+\fBsystemd-boot\fR(7)\&.
+.PP
+If the stub and/or the kernel contain
+"\&.sbat"
+sections they will be merged in the UKI so that revocation updates affecting either are considered when the UKI is loaded by Shim\&. For more information on SBAT see
+\m[blue]\fBShim documentation\fR\m[]\&\s-2\u[2]\d\s+2\&.
+.SS "genkey"
+.PP
+This command creates the keys for PCR signing and the key and certificate used for SecureBoot signing\&. The same configuration options that determine what keys and in which paths will be needed for signing when
+\fBbuild\fR
+is used, here determine which keys will be created\&. See the discussion of
+\fIPCRPrivateKey=\fR/\fB\-\-pcr\-private\-key=\fR,
+\fIPCRPublicKey=\fR/\fB\-\-pcr\-public\-key=\fR, and
+\fISecureBootPrivateKey=\fR/\fB\-\-secureboot\-private\-key=\fR
+below\&.
+.PP
+The output files must not exist\&.
+.SS "inspect"
+.PP
+Display information about the sections in a given binary or binaries\&. If
+\fB\-\-all\fR
+is given, all sections are shown\&. Otherwise, if
+\fB\-\-section=\fR
+option is specified at least once, only those sections are shown\&. Otherwise, well\-known sections that are typically included in an UKI are shown\&. For each section, its name, size, and sha256\-digest is printed\&. For text sections, the contents are printed\&.
+.PP
+Also see the description of
+\fB\-j\fR/\fB\-\-json=\fR
+and
+\fB\-\-section=\fR\&.
+.SH "CONFIGURATION SETTINGS"
+.PP
+Settings can appear in configuration files (the syntax with
+\fISomeSetting=\fR\fI\fIvalue\fR\fR) and on the command line (the syntax with
+\fB\-\-some\-setting=\fR\fB\fIvalue\fR\fR)\&. For some command line parameters, a single\-letter shortcut is also allowed\&. In the configuration files, the setting must be in the appropriate section, so the descriptions are grouped by section below\&. When the same setting appears in the configuration file and on the command line, generally the command line setting has higher priority and overwrites the config file setting completely\&. If some setting behaves differently, this is described below\&.
+.PP
+If no config file is provided via the option
+\fB\-\-config=\fR\fB\fIPATH\fR\fR,
+\fBukify\fR
+will try to look for a default configuration file in the following paths in this order:
+/run/systemd/ukify\&.conf,
+/etc/systemd/ukify\&.conf,
+/usr/local/lib/systemd/ukify\&.conf, and
+/usr/lib/systemd/ukify\&.conf, and then load the first one found\&.
+\fBukify\fR
+will proceed normally if no configuration file is specified and no default one is found\&.
+.PP
+The
+\fILINUX\fR
+and
+\fIINITRD\fR
+positional arguments, or the equivalent
+\fILinux=\fR
+and
+\fIInitrd=\fR
+settings, are optional\&. If more than one initrd is specified, they will all be combined into a single PE section\&. This is useful to, for example, prepend microcode before the actual initrd\&.
+.PP
+The following options and settings are understood:
+.SS "Command line\-only options"
+.PP
+\fB\-\-config=\fR\fB\fIPATH\fR\fR
+.RS 4
+Load configuration from the given config file\&. In general, settings specified in the config file have lower precedence than the settings specified via options\&. In cases where the command line option does not fully override the config file setting are explicitly mentioned in the descriptions of individual options\&.

+For all verbs except
+\fBinspect\fR, the first syntax is used\&. Specify an arbitrary additional section

+"\&.linux"

+.sp
+For the
+\fBinspect\fR
+verb, the second syntax is used\&. The section
+\fINAME\fR

+"text", the contents will be printed\&. If the third argument is given, the contents will be saved to file
+\fIPATH\fR\&.

This may be useful for example when the first initrd contains microcode for the CPU and does not need to be updated when the kernel version changes, unlike the actual initrd\&.

+Subsequent invocations using the config file (\fBukify build \-\-config=/etc/kernel/uki\&.conf\fR) will use this certificate and key files\&. Note that the
