Hi Sreangsu
mmmm...... 'read-only' in lilo.conf means mount the file system read only
during boot-up. Normally once the fsck is done (in the system startup
script), the file system would be remounted read/write. & as you pointed
out, you'd face quite a lot of problems if root partition is mounted
read-only.
my /etc/rc.S (Slackware) says:
<QUOTE>
*** ERROR: Root partition has already been mounted read-write. Cannot
check!
For filesystem checking to work properly, your system must initially mount
the root partition as read only. Please modify your kernel with 'rdev' so
that it does this. If you're booting with LILO, add a line:
read-only
to the Linux section in your /etc/lilo.conf and type 'lilo' to reinstall
it.
</QUOTE>
The above error is thrown if the / partition is mounted read-write by
kernel (& it's not UMSDOS). If / is mounted read-write by the Kernel,
then my startup script does not do an fsck also. I don't know the case
with Redhat, since I had only been using Slackware.
