I pretty much do this every day.  I have FC 16 installed on an external hard
drive.  I have a system at home and a system at work that are both set up to
boot from an external drive.  The work system has an Intel i3 CPU, Intel
graphics, etc.  The home system has an AMD Athlon CPU, ATI graphics, etc.  Not
sure about the sound hardware but the work system is from 2005 while the work
system is recent so little likelihood it's the same.  About the only part that's
not transparent is I have to run xrandr after I startx to get things to display
on the right monitors.

Carrying the external hard drive between locations definitely beats lugging a
system back and forth.

Cheers,
Dave

The situations where anything really needs to be done, are extremely rare.  
99% of the time, the kernel will boot just fine. The only likely confusion  
would be post-boot, with network interfaces changing. Perhaps audio will get  
confused.


I did something like this ~10 years ago, or so. While Windows was utterly  
baffled by the experience, Linux just yawned as if nothing out of the  
ordinarily happened. Would be surprised if it's any different now.


The only good thing to have is a rescue disk, so you can boot into rescue  
mode, and be able to chroot and rebuild your initrd easily, in the very  
unlikely event that will be necessary.

Yea. I was shocked when I moved my system disk from an
AMD system with a Radeon video card to an Intel i7 system
with the native Intel HD graphics and it booted right
up. I was certainly prepared to reinstall, but I didn't
have to.

You may have to tweak the network configuration, as it could be bound
to the ethernet MAC address.
All the rest will probably just work or be trivial to fix.

you HAVE got a current full backup haven't you? and if you do I'd say  
have a go at it, Fedora has been very resilient for me.
