'live' external hard drive
I have a usb harddrive that I use on a few different machines (music storage, etc.), and am inclined to use live CDs when using windows machines, so I thought if I could install linux on to the HD, I wouldn't need to use them.
Presumably doing a standard install would result in having a hardware setup fixed to whichever comp I have the HD attached to at the time?
I know I could just run a live CD iso off the drive, but I'd like to be able to update, add new software, and so on.
Can anyone recommend an installation that wouldn't be locked into the initial hardware setup, but would also be more than a fixed live CD?
Any suggestions would be appreciated,
Edit: Sorry, perhaps this post ought to have been in the newbie section. It's not really intended as a 'which distro' question, but rather whether this could be done with a standard one rather than a live CD.
