Very Computer

Hi all:  Just a short question.  With the new patchlevel release of the kernel,
there is a very nice option for mounting the root filesystem readonly at first.
I assume the intention of this is to allow an [e2]fsck of the root partition.
My root partition is an ext2fs partition, 16MB.

Question:
        How does one remount a partition that has been mounted readonly as a
        read/write partition?  And what is the correct file to put the [e2]fsck
        in?  /etc/rc?  Or does /etc/init have to be modified somehow?

Attempts at Answer:
        I have tried doing an e2fsck of / (on /dev/hda2) at the beginning of
        /etc/rc.  This works.  However, when I do e2fsck on other partitions,
        the output from '/bin/e2fsck -mrv /dev/hdaX' says that /dev/hdaX is
        already mounted!  So when are the filesystems being mounted -- before
        /etc/rc is run?  Then I try to mount the root filesystem, and that
        *doesn't* work.  My version of 'mount' doesn't appear to support the '-u'
        option.  The man page says something about this.  But if there is no way
        to remount the root partition as read/write, why do it at all?
        Does anyone know if there is a /bin/mount that *does* support the '-u'
        option?  And what is the correct syntax for 'mount -u'?

In short, if anyone is able to run e2fsck on their /, /user, etc. paritions at
boot-time with 0.99pl9, and then remount / as read-write, could you let me know
how you did it?  Like, what do your /etc/rc, /etc/fstab, /bin/mount files look
like (or what size and date are they)?

Why, thank you. :-)

You need a version of mount which will do this.  It is on the
wishlist. :-)  I expect that a new mount will be available pretty
soon, and it will be announced when it is.

In response to my posting, I have received correspondence from someone who states
that the /etc/rc file that comes with the SLS 1.02 installation has the options
to do the [e2]fsck and the remounting of the partition read-write already in it,
just commented out with # signs.  This would indicate that there is a fixed
version of 'mount' in the new SLS, which I have not verified myself, though I
intend to do it soon.  It would be nice to be notified of such
developments when they occur, however!  I am sure Stephen would concur.
