[uml-devel] synchronous hostfs

-----BEGIN PGP SIGNED MESSAGE-----


I'm running 2.4.26-um3.
I happen to be running hostfs with NFS underneath. 
I get core dumps from my application, and I want to gdb them outside
of the UML. I had to switch from core dump to NFS (which seems to fail
now) to putting them in /tmp (which is ramdisk), and then move them to
/var/tmp, which is hostfs. 

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. This now only has effect if I umount/mount the file
system. (I know have a /usr/local mount just for this, even though
/usr/local is inside of /)
It used to be that this was a problem only if the program was running.

Is there some way to defeat the caching that is occuring?
or even to just flush it? (other than umount)
