DESCRIPTION

22       systemd-makefs@.service, systemd-mkswap@.service, and
23       systemd-growfs@.service are used to implement the x-systemd.makefs and
24       x-systemd.growfs options in fstab(5), see systemd.mount(5). They are
25       instantiated for each device for which the file system or swap
26       structure needs to be initialized, and for each mount point where the
27       file system needs to be grown.
28
29       These services are started at boot, either right before or right after
30       the mount point or swap device are used.
31
32       systemd-makefs knows very little about specific file systems and swap
33       devices, and after checking that the block device does not already
34       contain a file system or other content, it will execute binaries
35       specific to each filesystem type (/sbin/mkfs.type or /sbin/mkswap). For
36       certain file system types (currently ext2/ext3/ext4(5), btrfs(5),
37       xfs(5), f2fs, vfat) and for swap devices, it will configure reasonable
38       defaults and set the file system label and UUID based on the device
39       name.
40
41       systemd-growfs knows very little about specific file systems and swap
42       devices, and will instruct the kernel to grow the mounted filesystem to
43       full size of the underlying block device. Nevertheless, it needs to
44       know the ioctl(2) number specific to each file system, so only certain
45       types are supported. Currently: ext4(5), btrfs(5), xfs(5), and dm-crypt
46       partitions (see cryptsetup(8)).
47
48       If the creation of a file system or swap device fails, the mount point
49       or swap is failed too. If the growing of a file system fails, a warning
50       is emitted.
