RFE? Re-detect hardware

[Les Mikesell]

Would it be possible to add a feature to rescue mode and/or the livecd 
to fix things up after a move to new hardware?  That is, check and re-do 
all of the stuff that happens during an install to build the initrd 
image in /boot, re-install grub,  set up X and the other 
hardware-related black magic that happens in an install?  The obvious 
use case would be where your motherboard fries and you move the disk(s) 
to another box with a controller that needs a different driver, but you 
get the same scenario if you've done a backup/restore or you want to 
convert something that has been running under vmware to real hardware. 
In the backup/restore case it may also be necessary to fix up /etc/fstab 
and/or partition labels to match but I'm not so concerned about the 
parts where the changes are known and intentional as I am about having 
to know as much as the installer does about matching hardware to drivers.

Does such a thing already exist, and if not, where is the right place to 
file an RFE?
