Описание (Description)
systemd-makefs@.service, systemd-mkswap@.service, and
systemd-growfs@.service are used to implement the
x-systemd.makefs and x-systemd.growfs options in fstab(5), see
systemd.mount(5). They are instantiated for each device for which
the file system or swap structure needs to be initialized, and
for each mount point where the file system needs to be grown.
These services are started at boot, either right before or right
after the mount point or swap device are used.
systemd-makefs knows very little about specific file systems and
swap devices, and after checking that the block device does not
already contain a file system or other content, it will execute
binaries specific to each filesystem type (/sbin/mkfs.type or
/sbin/mkswap).
systemd-growfs knows very little about specific file systems and
swap devices, and will instruct the kernel to grow the mounted
filesystem to full size of the underlying block device.
Nevertheless, it needs to know the ioctl(2) number specific to
each file system, so only certain types are supported. Currently:
ext4(5), btrfs(5), xfs(5), and dm-crypt partitions (see
cryptsetup(8)).
If the creation of a file system or swap device fails, the mount
point or swap is failed too. If the growing of a file system
fails, a warning is emitted.
