fstab and Grub
I grow tired of all the Label things going on in Fedora now. I wanted to
let a user mount and unmount file systems since I'm the only user...I
had this all working in Red Hat 9. Then I went to Fedora Core 4 and to
my dismay I found that HAL was writing fstab every boot up. So you
really didn't want to play with it any more.
Now on my FC6 I see that fstab and grub are not messed with by HAL any
more. So I set about to make things people readable. Here is what
"fdisk" finds on my two hard drives:
The number of cylinders for this disk is set to 19457.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

There is a lot of old linux partitions shown.
What I did then is edit fstab and grub.conf and replace the lables
with actual /dev/hda1 type devices.
My original fstab looks like this:
LABEL=/1234 / ext3 defaults 1 1
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
LABEL=+`àQñGM@O2RÕ{ÏA swap swap defaults 0 0
LABEL=ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ swap swap defaults 0 0
The swap listings were ugly!
Here is what it looks like now:
[root@k5d ~]# more /etc/fstab
/dev/hdb5 / ext3 defaults 1 1
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
/dev/hda2 swap swap defaults 0 0
/dev/hdb3 swap swap defaults 0 0
/dev/hdb7 /fc4 ext3 noauto, user 0 0
[root@k5d ~]#
For some reason the last line is not working right. I think maybe I need
to remember what I did. Maybe a # at the first and last line.
Grub is now looking like this:
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd1,6)
# kernel /boot/vmlinuz-version ro root=/dev/hdb7
# initrd /boot/initrd-version.img
#boot=/dev/hda

I have rebooted with all these changes and it comes up just as well
as always. Unless someone thinks this is real bad I will continue with
the project.
