Once I’ve been editing my mounted hard drives in
fileSystems and boldly switched to the new config without testing first.
This resulted in the OS getting dead frozen, my SSH connection died out and I could never connect back. Similarly, the OS were unresponsive upon boot, not accepting SSH and not serving anything that it were supposed to. It were a whole quest to get it switched to the last known good configuration, as its boot console were not accessible.
Is this an expected behavior? I’m worried of the OS getting completely incapacitated by a problem in just one fstab entry.
To add more details, I’ve been legacy-mounting a ZFS volume with
fileSystems(because automounting from ZFS filesystem
mountpointproperties were not working for some reason), and forgot that it requires setting
legacyexplicitly before mounting
