I would like to allow my users to run fsck after power loss without giving them the root password. When the system is improperly shutdown and boots into single-user mode, the user is asked for the root password before running fsck - how can I prevent this? I do not have access to the systems in order to input the password myself.
Thanks.

Hi,
I would recomment not allow normal user to run fsck as it can damage your file system if run incorrectly, if you dont
have to do an fsck on your machine edit the /etc/fstab and you should see something similar to:
LABEL=/home /home ext2 defaults 1 2
Notice the two on the end change that to a 0 for it to skip the fsck scan.
LABEL=/home /home ext2 defaults 1 0
Personally, I think the real problem here is you need run an Uninterruptable Power Supply, and switch to a journalling filesystem.
I'm serious. If this is a problem often enough that you are resorting to letting useres run fsck, then you definitely have a more serious problem underlying.
At worst you need to either chenge your kernel boot parameters and init.d scripts to automatically run fsck at boot, or you need to move to reiser/ext3 journalling filesystems and or get a UPS.
Otherwise, you are just asking for trouble. Might as well remove the HD's, run Live CD's, and mount /home off a battery backed, resiser fs server.

What distro?
Once I had this same problem on my RH boxes, I developed 3 solutions:
- I edited /etc/rc.d/rc.sysinit script and added '-y' flag to the fsck (it always answers yes to the fsck questions)
- I removed root password (asterix in /etc/shadow entry). After that user just need to hit enter at boot prompt for root password (+ sudo as root access)
- changed filesystem to reiserfs ;)
