Re: 2.4.20 Kernel and VFS

Hi all,

Yes, I've dropped off-list for a while - too busy to read email at the
moment!

However, I've returned so that I can post a follow-up to one of my own
problems - possibly bad form replying to your own posts, but better than
leaving a problem unsolved on-list!

The solution to the problem (below) was that the kernel needs to have
RAM disk and initrd support compiled in. (Duh! :-)

Cheers!

This may seem a bit weird, but that's okay, because it is weird.
