I get the following errors trying to getting Fiasco from your remote CVS:
eto@eto ~/l4/fiasco $ cvs -z3 -d :pserver:guest@os.inf.tu-dresden.de:/home/remote-cvs checkout l4linux-2.6 cvs checkout: Updating l4linux-2.6 cvs checkout: failed to create lock directory for `/home/remote-cvs/l4linux-2.6' (/home/remote-cvs/l4linux-2.6/#cvs.lock): Permission denied cvs checkout: failed to obtain dir lock in repository `/home/remote-cvs/l4linux-2.6' cvs [checkout aborted]: read lock failed - giving up
Any ideas?
