Description of problem:

I'm trying to test out a build failure with a fedora-rawhide-x86_64 build root using mock --shell.  When run during the build, the xauth command (as called by xvfb-run) appears to work okay.  But when I run under --shell I get:

mock -r fedora-rawhide-x86_64 --shell

Version-Release number of selected component (if applicable):

This host is running in enforcing mode.  If I switch to permissive, it works.

Perhaps the selinux plugin needs to be updated for new location of /selinux?

Comment 1 Clark Williams 2011-10-12 19:02:47 UTC

I suspect that the issue has to do with the way --shell setup the chroot (since it didn't do it the same way as --rebuild or --chroot). I've just refactored the code so that --shell and --chroot do the same setup steps as a --rebuild. 

I'd send you a patch but it's pretty big, so easiest thing would be to wait for 1.1.16 to hit brew. I'll try and ping you when it does.

Have you been able to check the behavior of the current mock with this command?

Comment 3 Orion Poplawski 2011-11-14 16:13:19 UTC
It appears to be working now, thanks!
