149. df Says, Cannot read table of mounted file systems.
A: There is probably something wrong with your /etc/mtab or /etc/fstab files. If you have a reasonably new version of mount, /etc/mtab should be emptied or deleted at boot time (in /etc/rc.local or /etc/rc.d/*), using something like
$ rm -f /etc/mtab*
Some old Linux distributions have an entry for the root partition in /etc/ mtab made in /etc/rc* by using rdev. That is incorrectthe newer versions of mount do this automatically.
Some old distributions also have a line in /etc/fstab that looks like:
/dev/sdb1 /root ext2 defaults
The entry for /root should read simply /.
