Allow a regular user to mount a removable filesystem defined in fstab.
The permitted user should also be able to unmount it using the standard option.
Which value is appropriate?
The fstab user option permits a regular user to mount the entry, and the mounting user can normally unmount it. Review implied security options.
Detailed explanation
nouserIncorrect. nouser explicitly prevents regular users from mounting.
owner-onlyIncorrect. owner-only is not the standard fstab option for this behavior.
userCorrect. user allows a regular user to mount the entry.
suidIncorrect. suid controls set-user-ID behavior, not who may mount.
