Is there a way to mount within CentOS 6.3 e.g. mount /mnt/a /mnt/b or mount /mnt/b (for /mnt/b in /etc/fstab), without the requirement of using the sudo command?

What are you mounting? Local block storage? Network shared? – Aaron Copley Aug 1 '12 at 14:32
Various network and local shares. – mcmu11en Aug 1 '12 at 14:49

If you can be precise about the device to mount, and the mount point, then you can delegate that power via the user option in /etc/fstab, eg:

/dev/sdd1       /mnt            vfat    user    0 0

which will allow any user to do mount /mnt.

@DotGeorge, for the man page entry, man 8 mount and go down to the section on 'non-superuser mounts'. There are also options for owner and group if you want only a subset of users being able to mount the specified filesystem. – cjc Aug 1 '12 at 14:29
Thanks for that, guys. I'm not sure why this didn't occur to me as I'm authenticating with a few of my shares using a credentials file. Cheers. – mcmu11en Aug 1 '12 at 14:33

Don't forget you can use LABEL or UUID to be less precise than the block device mapping. – Aaron Copley Aug 1 '12 at 14:33
@AaronCopley I've not used the UUID before. What will that give me - some level of abstraction? – mcmu11en Aug 1 '12 at 15:02

@DotGeorge Correct, every device has a UUID. It's actually more precise than device mapping since this can change on reboot. (I misspoke a bit before.) Run the command blkid to enumerate them on your host. There is likely already an example in /etc/fstab using it. (/boot, usually.) – Aaron Copley Aug 1 '12 at 15:07

You can add users to the fuse group to allow them to mount in userspace with fusermount.
