Hi,

We're trialling this at mythic-beasts.com. We've found no problems with yum /
up2date updating the packages but you have to make sure the UML image has
enough memory to run yum, e.g. 64MB + 128MB of swap should do.

With a vanilla 2.4.25 kernel patched for UML we've found threading issues,
e.g. installing the Java SDK & running java programs, we think we need to
patch with nptl, although we're considering using 2.6.5 instead.

Most of our trial customers so far wanted debian though so whitebox is sitting
on a back burner.

Yours,

Pete
