pkg: cache attempt failed: open-output-file: cannot open output file

[Neil Van Dyke]

server/built/test-fail issue on one of my packages, which looks like not
a package's fault (see below log).

In general, do you guys want to be emailed by developers of this kind of
thing with the build server, or should we just check back in 24 hours?

Thanks,

That certainly looks like a build-system error. I don't know why the
Linux instance (in a VM) decided part-way through that the filesystem
is read-only, and I haven't seen it in other runs. I forced a rebuild
for the package, and the problem didn't happen again.

Meanwhile, the pkg-build service now reports archiving failures (i.e.,
failures in the attempt to get a package for building). The "vlc" and
"kitco" builds currently fail at that level.
