[CentOS] Re: keep /boot, copy / from elsewhere?

on 10/16/2007 8:31 AM Les Mikesell spake the following:

How much is likely to break if you keep a locally installed /boot partition with it's anaconda-crafted module set in the initrd, but wipe and completely replace / and any other partitions with a copy from a machine that has somewhat different hardware? Assume both machines are running the same kernel versions and the change is done while running from the rescue CD or other livecd boot.

If you have similar boot controller, it could work. But if boot controller changes, and needs a different driver, it won't boot. You will get a panic when it can't find the root.
