[ale] /tmp set to read-only on boot (need help)

[Ryan Fish]

Due to /tmp not being listed in /etc/fstab or /etc/mtab that command (mount
/tmp -o rw,remount ) does not work.

[root at server02 root]# mount /tmp -o rw,remount
mount: can't find /tmp in /etc/fstab or /etc/mtab


[root at server02 root]# more /etc/fstab
