<title>Description</title>
|
||||
|
||||
<para><filename>systemd-machine-id-commit.service</filename> is
|
||||
a service responsible for commiting any transient
|
||||
<filename>/etc/machine-id</filename> file to a writable file
|
||||
system. See
|
||||
<citerefentry><refentrytitle>machine-id</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
||||
for more information about this file.</para>
|
||||
|
||||
<para>This service is started shortly after
|
||||
<filename>local-fs.target</filename> if
|
||||
<filename>/etc/machine-id</filename> is an independent mount
|
||||
point (probably a tmpfs one) and /etc is writable.
|
||||
<command>systemd-machine-id-commit</command> will then
|
||||
write current machine ID to disk and unmount the transient
|
||||
<filename>/etc/machine-id</filename> file in a race-free
|
||||
manner to ensure that file is always valid for other
|
||||
processes.</para>
|
||||
|
||||
<para>Note that the traditional way to initialize the machine
|
||||
ID in <filename>/etc/machine-id</filename> is to use
|
||||
<command>systemd-machine-id-setup</command> by system
|
||||
installer tools. You can also use
|
||||
<citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
|
||||
to initialize the machine ID on mounted (but not
|
||||
booted) system images. The main use case for that service is
|
||||
<filename>/etc/machine-id</filename> being an empty file at
|
||||
boot and initrd chaining to systemd giving it a read only file
|
||||
system that will be turned read-write later during the boot
|
||||
process.</para>
|
||||
|
||||
<para>There is no consequence if that service fails other than
|
||||
a newer machine-id will be generated during next system boot.
