I am installing Red Hat Linux using DISK DRUID to partition my hard drive. After partitioning all of the partitions except the last partition, let say I have 682m left unused on my hard drive, so I partion the last one and with 682m and using the option "use all space up to(MB)" 682 and it's going through the installation process. Once everything is finish, I looked at the partition and I got all of the partion right except this:

Filesystem Size Used Avail Use% Mounted on
none 62m 0 61m 0% /dev/shm


The questions here is why I have this partion in here. Seem to me that I didn't use all of the space available, but I did tell Linux to use all of the space up to the max.

What did I do wrong, could someone please advise me on this issue???

thanks
