Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I’m very new on using Linux (Debian) and have following question. I installed debian and during the process also created separate partition for /tmp. How can I now make sure that server programs use that special partition /tmp instead of /tmp folder under /root partition?

You're probably referring to just a /tmp folder under the / partition (seen a lot). But it your case, /tmp is not just a directory under the / partition, it's a seperate mount point (just like / is the root mountpoint).

In other words, the /tmp you see is not a sub-directory of /, it's a seperate partition on your hard disk that can just be accessed through this path. You can see it as a sort of shortcut to that part on your harddisk. Filling up the /tmp will not affect the disk space usage of your / partition.

If you run cat /etc/fstab (which is the filesystem table file, holding all of your partition data) you can check out what your partitions are configured like and you should see /tmp as a seperate line.

Thank you for quick answere, doing cat /etc/fstab gave this output: proc /proc proc defaults 0 0 none /dev/pts devpts gid=5,mode=620 0 0 /dev/md0 none swap sw 0 0 /dev/md1 /boot ext3 defaults 0 0 /dev/md2 / ext3 defaults 0 0 /dev/md3 /tmp ext3 defaults 0 0 /dev/md4 /vz ext3 defaults 0 0 –  Mark Dec 16 '12 at 13:16
    
The line /tmp ext3 defaults 0 0 means that /tmp is indeed a seperate partition, so every application will use that partition and won't fill up your primary partition. –  Oldskool Dec 16 '12 at 13:19
    
OK, so programs will use that partition by default without me needing to edit anything? thank you for clearing it! –  Mark Dec 16 '12 at 13:24
