>Description:
	trying rump_ffs on a filesystem image with unsupported features
	(like a unsupported flag in fs_flags) fails with EINVAL.
	The kernel also does a uprintf() with details about the unsupported
	feature, but this doesn't show up even with RUMP_VERBOSE.
	I would expect this message to go to stderr.
>How-To-Repeat:
	This can probably be repeated by filling up the rump_ffs-mounted
	filesystem; this triggers the uprintf() at the end of
	ffs_alloc(), ffs_realloccg() or ffs_valloc().

State-Changed-When: Thu, 13 Jan 2011 13:04:25 +0200
State-Changed-Why:
rump processes do not have a controlling tty, so uprints are 
discarded.  Maybe they should have one by default?
