systemd-makefs@.service, systemd-mkswap@.service,
systemd-growfs@.service, and systemd-growfs-root.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). For certain file system types (currently
ext2/ext3/ext4(5), btrfs(5), xfs(5), f2fs, vfat) and for swap
devices, it will configure reasonable defaults and set the file
system label and UUID based on the device name.
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.
