Karel Zak 3519d230c8 fstab-generator: add x-systemd.requires and x-systemd.requires-mounts-for ... Currently we have no way how to specify dependencies between fstab entries (or another units) in the /etc/fstab. It means that users are forced to bypass fstab and write .mount units manually. The patch introduces new systemd fstab options: x-systemd.requires=<PATH> - to specify dependence an another mount (PATH is translated to unit name) x-systemd.requires=<UNIT> - to specify dependence on arbitrary UNIT x-systemd.requires-mounts-for=<PATH ...> - to specify dependence on another paths, implemented by RequiresMountsFor=. The option may be specified more than once. For example two bind mounts where B depends on A: /mnt/test/A /mnt/test/A none bind,defaults /mnt/test/A /mnt/test/B none bind,x-systemd.requires=/mnt/test/A More complex example with overlay FS where one mount point depends on "low" and "upper" directories: /dev/sdc1 /mnt/low ext4 defaults /dev/sdc2 /mnt/high ext4 defaults overlay /mnt/merged overlay lowerdir=/mnt/low,upperdir=/mnt/high/data,workdir=/mnt/high/work,x-systemd.requires-mounts-for=/mnt/low,x-systemd.requires-mounts-for=mnt/high https://bugzilla.redhat.com/show_bug.cgi?id=812826 https://bugzilla.redhat.com/show_bug.cgi?id=1164334		2015-05-18 16:07:52 +02:00
