Ha! This is a bit different but interesting anyway. I didn't know that it was possible to use x-systemd.* options in /etc/fstab [...] > I haven't any idea how this fits in with having udisks on the system or > remounting a disk rw, or even how it fits your objectives. For the remounting I'm not worried. My use case is that I have about 10 or 15 hard disks that I want to automount in ro because... I only need to read from them and I want to avoid making accidental changes. I expect that I don't need to change /etc/fstab with the UUID / LABEL of each one. I guess (untested) that I could do: " /dev/sdc1 /mnt/read-only auto ro,other_options 0 0 " But I think that I would prefer to change the auto-mounter instead of changing /etc/fstab and assume that they will come as sdc1 (plus some have different partitions; and they have ext4, vfat and reiserfs for what I remember but "auto" should be enough for this).
