Hmm - were you putting the core dumps inside a hostfs mount, right? This has been reported to fail badly with 2.4.26-3um... the hostfs contained in 2.4.24-1um and 2.4.27-1bs (this tree is from me, on my homepage) is stable, while the one in 2.4.24-2um and subsequent releases isn't. > Still, I now have to use unique file names, or things get confused > between host and guest. > > I also like to do: > "make DESTDIR=/uml/root/file install" > from outside.

(other than umount) Hmmm, I don't know this... probably giving "sync" inside UML should work. I remember that Jeff said that he made hostfs asynchronous in those releases on purpose (for performance, IIRC), and this is not bad. -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
