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 think this should work:  After the first install change the volume 
labels on the existing partitions (with e2label), changing /etc/fstab 
at the same time.  Then, you can use the labels the installer wants on 
the second install.

How to install two linux OSes on the same PC

[Narsimha Reddy Challa]

Originally to: All

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

Well, you could change the partition type of the existing installation,
in hope that the installer will ignore it.  It doesn't matter to linux
what the partition type is as long as it has a filesystem of the type
expected in /etc/fstab.

Edit properly in that menu where it ask's for partition info for installing.

I have Redhat 7.2, slackware gentoo and peanut all on one disk.

Slackware was installed first, then redhat.

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.

How to install two linux OSes on the same PC

[Narsimha Reddy CHALLA]

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

How to install two linux OSes on the same PC

[Narsimha Reddy CHALLA]

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

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 /etc/lilo.conf of  first one and 
/sbin/lilo,  I can boot both of them using.
