“window -m cmd” will run the command in the same namespace, forked, but in new

“-m” is for “mount”, an alternative way of communication with the window system
to /dev/wctl which is default.

A backport of fontsrv from p9p to Plan 9 is almost complete, based on an
earlier port of freetype library found at mirtchovski.com. Besides TTFs, it
happens to render most of the Type 1 fonts already there, enabling their use in
devdraw programs.
Coming soon.

U9fs(4) misuses Fcall.afid in its p9any authentication module.
The afid field of Fcall structure is only valid with Tauth or Tattach.
Tread, Twrite, Tclunk should use rx->fid instead. It's been lucky so
far to get the job done because rx->afid survives from previous
Tauth/Tattach. The issue pops

One of available options is to modify venti so it prepends the

APE programs which require libmp fail to link due to unresolved
mallocz symbol. Easily solved by providing a local implementation,
but why: it's already there - in an alternative form though:
cpu% nm /386/lib/ape/libap.a | grep -i mallocz

The problem also disappears when a severe latency induced on the path

APE implements rename() in terms of wstat or copying. It's just
doesn't try to work around failing wstat (that's perhaps a good thing)
while mv does.
Is there a specific reason of forbidding wstat for 'none' in fossil
(/sys/src/cmd/fossil/9p.c:130,133)?
This causes APE rename() to fail almost always
(/sys/src/ape/lib/ap/plan9/rename.c:43)
Perhaps rename() should be fixed to match mv (/sys/src/cmd/mv.c:/^mv1)
to go around this?

why not to have what's in 9setup directly in 9.mk?
Uname in Tauth/Tattach indeed seem to be irrelevant for p9any but as
it is external to 9P this may be a provision for other possible auth
schemes where the uname may be the only place to provide an indentity
being authenticated...
devmnt always uses up->user for Tauth/Tattach no matter what an auth
protocol would yield (/sys/src/9/port/devmnt.c:281). Stock 9P servers
tolerate this and check Tattach.uname to match Tauth.uname but use
t.cuid or t.suid as the true user identity (unless no auth required).
Anyway, simply trustin
al use,
howerver, is not that clear: cwfs for 9p2k uses t.suid; while fossil,
exportfs, cpu -R and cwfs for old9p check against t.cuid. Comments in
/sys/include/authsrv.h:58,76 appear somewhat opaque until authsrv(6)
and p9sk1 client/server code in factotum are carefully studied.
