Granted Slack runs on a philosophy of using the most stable, and "tried and tested" software, it'd be nice to see things be easier to move between distributions...
The 2 most successful installs I've had, thus far, have been Red Hat and Mandrake.
I was out of town for 2 weeks so I had to put installing Kubuntu on hold, but am going to try it in May. Hopefully I will have good results with it.
