systemd-remount-fs.service, systemd-remount-fs - Remount root and
kernel file systems
Синопсис (Synopsis)
systemd-remount-fs.service
/usr/lib/systemd/systemd-remount-fs
Описание (Description)
systemd-remount-fs.service is an early boot service that applies
mount options listed in fstab(5), or gathered from the partition
table (when systemd-gpt-auto-generator(8) is active) to the root
file system, the /usr/ file system, and the kernel API file
systems. This is required so that the mount options of these file
systems — which are pre-mounted by the kernel, the initial RAM
disk, container environments or system manager code — are updated
to those configured in /etc/fstab and the other sources. This
service ignores normal file systems and only changes the root
file system (i.e. /), /usr/, and the virtual kernel API file
systems such as /proc/, /sys/ or /dev/. This service executes no
operation if no configuration is found (/etc/fstab does not exist
or lists no entries for the mentioned file systems, or the
partition table does not contain relevant entries).

Note: systemd-remount-fs.service is usually pulled in by
systemd-fstab-generator(8), hence it is also affected by the
kernel command line option fstab=, which may be used to disable
the generator. It may also pulled in by
systemd-gpt-auto-generator(8), which is affected by
systemd.gpt_auto and other options.
