Yes, but by using Knoppix apps these shouldn't crash, being independent
from the chroot environment.
My concerns were mostly about the peril of X crashing (and being
temporarly unable to come again up) vs memory usage penalty with a
knoppix (but chrooted environment, no apps crashing).
However I guess I'll start the recompile tonight and eventually spend
tomorrow reading and cleaning home...
