+ * COMMON_SYSTEM_SPECIFIERS:
+ * %a: the native userspace architecture
+ * %b: the boot ID of the running system
+ * %B: the OS build ID, according to /etc/os-release
+ * %H: the hostname of the running system
+ * %l: the short hostname of the running system
+ * %m: the machine ID of the running system
+ * %o: the OS ID according to /etc/os-release
+ * %v: the kernel version
+ * %w: the OS version ID, according to /etc/os-release
+ * %W: the OS variant ID, according to /etc/os-release
+ *
+ * COMMON_CREDS_SPECIFIERS:
+ * %g: the groupname of the running user
+ * %G: the GID of the running user
+ * %u: the username of the running user
+ * %U: the UID of the running user
+ *
+ * COMMON_TMP_SPECIFIERS:
+ * %T: the temporary directory (e.g. /tmp, or $TMPDIR, $TEMP, $TMP)
+ * %V: the temporary directory for large, persistent stuff (e.g. /var/tmp, or $TMPDIR, $TEMP, $TMP)
