Dear all, I've been using colinux (http://colinux.sf.net) to run FC4 for quite a while. Once FC5 was released, I promptly upgraded -- only to find udev complaining that the colinux kernel (2.6.12) was too old for this version of udev. As a result, none of the required device nodes got created and I had an unusable system on my hands. Eventually, I did manage to get to a root shell and downgraded udev to that from FC4 updates (+ hotplug). This solved the problem and FC5 will boot. So far so good... My question is, are there any potential problems I should watch out for? I only need udev to create the block devices -- since I obviously won't be adding any "other" hardware to it. Accroding to the coLinux developers, the major problem that they have right now is that after 2.6.12, the base memory management in the kernel was changed; and since coLinux relied on the older method it is proving to be quite a challenging to move on to newer kernels. The coLinux project is quite nice since it runs at speeds very similar to (or faster than) vmware. But right now, they only have 2 active developers -- if anyone one is interested, I'm sure they could use the help. TIA, -M
