How to make Ubuntu adapt to new computer/hardware on every boot?
 

I have installed an Ubuntu 10.04 LTS distro on a external mobile HDD with 500 GB. I want to use the HDD as a Flash USB, so that I can work with my own OS on every computer I use. I tried to isntall the Flash distributions on the HDD, but they could manage to set the casper file to max 4 Gb, and I want to use the whole HDD.

So I installed Lucid Lynx.

The UUID's of root and swap partitions are static, and are written correctly in /boot/grub/grub.cfg, /etc/fstab and /etc/initramfs-tools/conf.d/resume.
It runs perfectly most of the time on different computers, but sometimes fails on e.g. reboot.

So the question is: Is there anything I can do to make Linux adapt to the new hardware on every boot? Any files to modify or delete?

It should "just work" so when you say it "sometimes fails" please be specific (complete error messages etc.) so we can help you troubleshoot.

Hey,
Found the problem :)

/etc/initramfs-tools/conf.d/resume wasn't correct as I thought - works like a charm!
