This actually touches on this quesition: what should be the
criterion for deciding that a rust update is "safe"?  That's not
at all clear to me.

Obviously, cutting a pkgsrc branch where the build of www/firefox
is broken because of rust on NetBSD/amd64 9.x would be very bad.
Probably the same can be said for NetBSD/i386 9.x, though perhaps
less so, particularly if the problem isn't actually caused by

However, we build rust on more ports/targets which either has
never managed to build firefox (looking at macppc and probably
armv7(?)), or where it's continually troublesome for mostly other
reasons (sparc64).  Obviously "firefox builds" can't be a
criterion for those ports/targets.

Borderline is probably NetBSD/i386 8.0 -- my recent attempts
revealed a needed fix for multimedia/dav1d (thanks, Nia!), and a
dubious construct trying to use a clang-specific option with gcc
for NetBSD 8.* in  These obviously have
nothing to do with rust itself, but are indicative that this
particular port/OS-version combination doesn't get sufficiently

Borderline is perhaps also NetBSD/aarch64(?) -- do we have
firefox building and working on that?  The build resources I have
available are however inadequate to build www/firefox on aarch64
in acceptable time, it's barely sufficient to test-build rust,

A large user of rust is of course the rust compiler itself.  If
there is a fundamental fallout for one of the ports/targets we
build for which would break firefox, would not that also prevent
the build of rust itself?
