One problem on FCOS is that the root directory is immutable, as such in order to mount arbitrary paths from the host we must make it mutable again and create these dir on boot in order to be able to mount there. The current logic was racy as it used one unit for each path and they all did chattr -i /; mkdir -p $path; chattr -i / and systemd can run these units in parallel. That means it was possible for another unit to make / immutable before the unit could do the mkdir. I pointed this out on the original PR[1] but we never followed up on it... Now this here changes several things. First have one unit that does the chattr -i / (immutable-root-off.service), it is hooked into remote-fs-pre.target which means it is executed before the network mounts (virtiofs) are done. Then we have another unit that does chattr +i / (immutable-root-on.service) which turn the immutable root back on after remote-fs.target which means all mount are done at this point. Additionally the automount unit is removed because it does not add any value for us and it was borken anyway as it used the virtiofs tag as path so systemd just ignored it.
