glibc error reports go to the bit bucket in koji

[Roland McGrath]

IMHO koji (and mock for that matter) ought to be running the builds inside
a captive pty whose ouytput it logs anyway, even if they redirect
everything.  You never know what crazy nonsense some package is going to try.

You can put LIBC_FATAL_STDERR_=1 in the environment to get those messages
to stderr instead of /dev/tty.  setuid programs will still use /dev/tty.
Or, it would use stderr by default if there was no /dev/tty.

If you're not going to capture the tty output, then you really should
disassociate from the tty (setsid) so /dev/tty does not work at all.
I'd call the failure to do one or the other of these a bug in mock or koji.


Thanks,
Roland
