DESCRIPTION
       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.
