Hi All,
I want to do two different linux installations rh 7.2 and rh
8.0 on the same pc with single hard disk. I installed the rh 7.2 in
partitions say /dev/hda5 ( /) , /dev/hda6 (/home) , /dev/hda7 (
/usr) ,
/dev/hda8 ( /tmp),... /dev/hda11 etc.
But how can I install the rh 8.0 in partitions say /dev/hda12
( as "/" ) ... etc ?? Since the installer won't allow as there
already exists a "/" partition for the rh 7.2 and tries to override
it with the root partition of rh 8.0. So I tried giving a different
lable to the root partition of rh 8.0 say /root1 and other partitions
as /root1/usr, /root1/home, /root1/tmp etc. But here also the installer
is looking for the partition named "/" and without that the installation
is not happening.
Please give your suggestions on how to resolve this problem.
At present my partition table with single installation (rh 7.2) is,
[root@creddy-pc root]# fdisk -l
Disk /dev/hda: 255 heads, 63 sectors, 2434 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 261 2096451 6 FAT16
/dev/hda2 262 2434 17454622+ 5 Extended
/dev/hda5 262 522 2096451 6 FAT16
/dev/hda6 523 653 1052226 83 Linux
/dev/hda7 654 1175 4192933+ 83 Linux

/dev/hda11 1502 1566 522081 83 Linux

I'm not remembering much about the RH install, but have you tried using
a console durring the early part of the installand repointing the mount
points to where you want them? This is a question that is best for
RedHat's own lists. I know this can be done as I've done it in the
past. It's been awhile since I've admined RedHat systems for
developers. I'm only admining Debian systems now.

I believe the problem is related to Redhat's use of partition labels
by default on 7.x and 8.x. Makes it easy if the drives master/slave
changes but causes problems for other things like this.
For example, my /etc/fstab looks like:
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext2 defaults 1 2
LABEL=/home /home ext3 defaults 1 2
/dev/hda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
Attempting to boot a system with two drives (or multiple partitions on
the same drive) configured like this will confuse the system. So the
first step would be to change the LABEL= lines to /dev/<device> (i.e.
/dev/hda1 /boot ......etc.)
Next issue is how you want to boot the two systems. One boot partition
or two? With one boot, make a copy of what is already there, then
install the new system, allowing it to overwrite the old. Then merge
the two boot partitions by hand. They will already be a different
kernels, etc. so it shouldn't be too hard.
Then I would recommend booting the second system or mounting its drives
in the first temporarily and making similar changes to its fstab that we
did to the first.
Then reboot and I believe it should work....
Good luck,
Dave V.

Thanks a lot for your help. It really worked with disk driud. It
cleverly managed the name conflicts of lables i.e. for first
installation the root is "/" and for the second installation the root
lable is "/1". After editing the /etc/lilo.conf of first installation
and updating the MBR with /sbin/lilo appropriately, I can boot both of them.
