fstab entry added by GUI Disks utility seems ill-formatted but works?

lr flag

The Disks utility (gnome-disks) added this entry in /etc/fstab:

UUID=[UUID] [mount pount] auto nosuid,nodev,nofail,x-gvfs-show 0 0

Based on numerous examples and on info fstab, auto is where the filesystem type (ext4 in this case) should be, and then auto,, with a comma, should start the list of options.

But the partition is mounted at startup, so auto is working. Is fstab lax about formatting? Is the Disks utility sloppy about formatting?

(Why I care: I'm about to install Ubuntu server on a new hardware system and want to add an appropriate fstab entry manually.)

No, it is not ill-formatted; the auto keyword may be used as both a filesystem type and a mount option. From man mount:

(as a filesystem type):

          If  no  -t  option  is  given, or if the auto type is specified,
          mount will try to guess the desired type.

(as a mount option):

   auto   Can be mounted with the -a option.

In your fstab-line auto is indeed the third field and the filesystem-type.

In the forth field which contains the mount options seperated with a comma there is no need to add the auto-option because it is default and this default will be used. If you don't want a partition to be automatically mounted, you'd have to use the noauto- option.

Here a short list of default mount-options:

rw, suid, dev, exec, auto, nouser, async

You can find such information with man mount.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
