Convert RHEL 5.1 Desktop DIsk Image to Laptop Image
 
Hi,

I've aquired a desktop that has a specific set of applications and apparent services that no matter what i've tried i can't get running on the laptop i need to get it running on.

It's a RHEL 5.1 Server image that I have spent the last 3 days trying to get working on the laptop with very little progress. HW specs on both are intel Core 2 Duo, 4 GB Ram, 120 GB hd, but Desktop is HDA, Laptop is SDA.

I've tried:
1) Ghosting entire disk from Desktop to Hardrive, with GRUB pointed in the right direction. Kernel panics on "can't find /dev/root"
2) Tried Fixing the init in initrd to point to the new /dev/sda, but no luck. It contains ide and sata modules.
3) Booted without an initrd - kernel panic, no /dev/root/
4) Using the same harddrive parition as desktop, installed RHEL5.1 again. Copied contents of /boot/ to a flash disk and then applied old ghost. Loaded rescue disk and copied new contents of flash disk back to /boot. Modified grub.conf to point to new laptop builds. Booted it, kernel booted, "just" got into X when crashed. ran in Telinit 1, ran kudzu. Never booted again.

I think i need to go back steps 1 to 4, and then do something different on the first boot.

I've tried virtualising this, but the virutalisation i've tried slowed the machine down a lot so it was no longer useable - it's a signal processing tool that needs to run in real-time.

Any ideas on the "right" way to do this?

Thanks in advance.

Can't you install RHEL to your laptop the same way you installed it to your desktop? Can you use unetbootin to install RHEL to a pendrive? I'm assuming you're dealing with some kind of ISO here. How about booting to a live CD you know works, mounting the RHEL partition, and then chrooting into it? Just some suggestions.

Hi Kinetic,

I'd tried that, but the installation instructions were "install RHEL, copy CD contents to /usr/, run "make go".

And with commands that simple, it's failing, but i can't work out why. I get no verbose output from the make files, tracing through them ( 104 make files in total ) i can't work out what is failing, ie no idea on dependanice issues etc.

SO i thought it would be easier to ghost it over so all the dependancies etc are installed, confs are aligned, and it "should" work once the new H/W is configured....

How wrong i was!

It really sounds like it isn't worth the trouble. What did you need it for anyway?
