    botched fstab

    Yesterday i rolled up a new 2.4.22 kernel and also removed the 'LABEL' references from the fstab ( i guess redhat puts them there).....anyhow, instead of /dev/hda3 for mounting / i put /dex/hda3

    now when i reboot i get a 'maintenance' login to correct the problem.

    i login...
    do a 'df'.....it shows /dev/hda3 mounted as /
    all is well so far.
    then i go to load in fstab into vi and it wont let me save the changes...
    it will tell me that the filesystem is 'read only'

    i dont have a boot disk made....nor a cd drive installed ( i did when i installed it but took it out)

    is there a way i can save this change to the fstab file without having to have a boot floppy, reinstall the cdrom drive, or pull the drive and mount it on another nix system?

    Once you're in Single User mode, you should be able to issue the following command:

    > mount -o remount,rw / /

    This will mount the root filesystem as read/write and allow you to change the file.

    If this doesn't work, try reading the man page for mount and check the syntax. I'm not in front of a Linux console, so I stole that command off the net.

    you may also have to issue the ! option with vi in order to force the save, depending on its permissions

    thanks Satanic Atheist. I will try that when i get home.

    dkeav, thanks for your input too. i tried that as well last night and it still wouldn't fly. i even tried to copy the fstab to fstab.old and edit that but the copy wouldnt work either....mentioning 'read-only filesystem'

    If the remount command posted above does not work (it should though), you can try

    mount -o remount,rw /

    or

    mount -o remount,rw /dev/hda3 /
