This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

<title>Description</title>
|
|
|
|
<para><filename>systemd-fsck@.service</filename> and
|
|
<filename>systemd-fsck-root.service</filename> are services
|
|
responsible for file system checks. They are instantiated for each
|
|
device that is configured for file system checking.
|
|
<filename>systemd-fsck-root.service</filename> is responsible for
|
|
file system checks on the root file system, but only if the
|
|
root filesystem was not checked in the initramfs.
|
|
<filename>systemd-fsck@.service</filename> is used for all other
|
|
file systems and for the root file system in the initramfs.</para>
|
|
|
|
<para>These services are started at boot if
|
|
<option>passno</option> in <filename>/etc/fstab</filename> for the
|
|
file system is set to a value greater than zero. The file system
|
|
check for root is performed before the other file systems. Other
|
|
file systems may be checked in parallel, except when they are on
|
|
the same rotating disk.</para>
|
|
|
|
<para><filename>systemd-fsck</filename> does not know any details
|
|
about specific filesystems, and simply executes file system
|
|
checkers specific to each filesystem type
|
|
(<filename>/sbin/fsck.*</filename>). These checkers will decide if
|
|
the filesystem should actually be checked based on the time since
|
|
last check, number of mounts, unclean unmount, etc.</para>
|
|
|
|
<para>If a file system check fails for a service without
|
|
<option>nofail</option>, emergency mode is activated, by isolating
|
|
to <filename>emergency.target</filename>.</para>

<title>Kernel Command Line</title>

<listitem><para>One of <literal>auto</literal>,

|
<literal>force</literal>, <literal>skip</literal>. Controls
|
|
the mode of operation. The default is <literal>auto</literal>,
|
|
and ensures that file system checks are done when the file
|
|
system checker deems them necessary. <literal>force</literal>
|
|
unconditionally results in full file system checks.
|
|
<literal>skip</literal> skips any file system
|
|
checks.</para></listitem>

<literal>yes</literal>, <literal>no</literal>. Controls the

mode of operation. The default is <literal>preen</literal>,
|
|
and will automatically repair problems that can be safely
|
|
fixed. <literal>yes</literal> will answer yes to all

questions by fsck and <literal>no</literal> will answer no to

all questions. </para></listitem>
