    rw and ro

    Hi

    re Darrens
    The only gotcha you must remember is to issue a rw before starting otherwise no changes will be made, and after finishing issue a ro to put the file system back to read only.
    I have frequently wondered:

    If one reboots without resetting ro does it matter - presumably the OS reboots into ro?

    How does one read the status that the OS is currently in? (Other than attempting to save an Edit?

    So is it critical if one forgets to resume ro status?

    Yes it matters, see below. It will automatically mount root in Read Only

    [TiVo [p0] ~]# mount
    /dev/hda4 on / type ext2 (ro)
    /dev/hda9 on /var type ext2 (rw)
    /dev/hda2 on /hack type ext2 (rw)
    /proc on /proc type proc (rw)

    Also shown in TWP

    Yes, there is a chance of a file becoming corrupted if left in RW when rebooting.

    Peter.

    PS don't forget /var & /hack are always RW, don't make them RO.
