Bootup problems (old Gentoo system)

How do I change to a ro mounted partition to a rw without rebooting?

umount /path/to/partition

edit entry in /etc/fstab so that it's rw

mount /path/to/partition

Alright, I tried that, so I'll explain the situation a bit more. I managed to screw up my config files, I kept getting this error on bootup (Press Ctrl D to continue or enter root password) When I got booted I changed the entry in fstab for the type of file system. It had XFS, and I know it's ext3, but I typed ext2 by mistake. When I rebooted, I'd get the same error. When I press Ctrl D to continue, it reboots. If I try and enter a password I get a command prompt. I can't edit anything because /root was mounted as ro. I tried to umount it, but it still says it's ro. How can I fix this?

PS. I knew updating my Config files would mess up!

Use your livecd and mount your root partition to edit the files.

Thanks! That worked for letting me edit the fstab. But I keep getting a error telling me that it would not mount /dev/ROOT at ext2. I changed the setting in the fstab to ext3. It is telling me the following:

"fsck.ext3: No such file or directory while trying to open /dev/ROOT
/dev/ROOT:

The Superblock could not be read or does not describe a correct ext2
file system. If the device is valid and it really contains a ext2 filesystem
(and not SWAP or UFS, or something else) then the superblock is corrupt, and you might try running e2fsck with a alternate superblock:
e2fsck -b 8193 <device>

*filesystem couldn't be fixed

Give root password for maintenance
(or press CTRL D for normal startup)"

If I press ctrl D it reboots, if I give a password, I can get in to a shell. I tried remounting the / partition and editing the fstab to reflect a ext3 partition and rebooted. I get the same thing. I tried running fsck.ext3 and it reported no errors. What am I missing? How can I get this running again?

Thanks, Walter

Have you tried changing fstab to point to the actual device instead of /dev/ROOT?

I just got it. Thanks for the help... just a few more things I need to figure out and I'm back to normal!
