use mtab as fstab?hi

rgiggs · 05-28-2004, 02:24 AM

hi,
as root, i accidentally overwrote fstab, so i just copied mtab to fstab, restarted, and the system seems to be running fine. any comments on using mtab as fstab?
also, i expected root to have noglobber set. now that i find out it isn't set, how can i make it that root always has noglobber?
thanks.

1. mtab contains the mounted fs, so any fs that wasn't mounted (e.g. /mnt/cdrom) may have lost it's configuration. Also if you use automount, it will write in mtab too, so you'll have some lines in fstab that shouldn't be there.

2. not sure what noglob is, but I suggest to put a 'alias cp="cp -i"' and 'alias mv="mv -i"' in /root/.bashrc
You can place there any command to be exec when opening a terminal

hi,
i have those aliases. noglobber prevents redirecting to an existing file. for example, this was how i screwed up fstab: cat > /etc/fstab. i meant to do cat >> /etc/fstab. with noglobber, the command would've failed. to force it, must do >!. i guess i'll just try 'set noglobber' and see what happens.
thanks.

Thank you for making me discover this useful option.
I googled for it and foud this: http://www.jsanten.demon.nl/linux/sh...ng/index1.html

"To activate noclobber you use set -C"
