Hi,
OK, thanks for the clue.
Unfortunately, this (devfs-posix.c in 9vx):
if(perm & ~(DMDIR|0777))
error(Ebadarg);
generates the error, and the values of DMEXCL and DMAPPEND do not seem
to fit into Unix permissions. So these won't work in 9vx as long as
the host filesystem is used*.
------------------------------------------------
* Unless the host FS is ext?fs and the kernel supports extended
attributes which may require specific patches
