doesnt prevent mock builds, simply produces annoying log messages.

Should be filed against selinux-policy.
Comment 3 Daniel Walsh 2007-11-26 10:00:16 EST
This is caused by a mislabling of the mock build direcrtory  /dev/null should be
labeled null_device_t not dev_log_t.  I think the true solution to get mock to
run in a context that does not transion to confined domains, so these avc's dont

Thanks for the help. I have fixed this in mock by doing a "chcon
--reference=/dev/FILE  /mock/build/root/dev/FILE". 

This fixes this issue for all of the /dev/ entries in mock. There are still a
couple other denials that dont have file details:

SELinux is preventing /sbin/depmod (depmod_t) "search" to (var_lib_t).
SELinux is preventing useradd (useradd_t) "read write" to (var_log_t).
SELinux is preventing tzdata-update (tzdata_t) "search" to (var_lib_t).

I'm not sure how to fix these because it does not list the path it is trying to

Can you explain more about "get mock to run in a context that does not transion
to confined domains"? I dont follow this.

This specific bug I am going to mark as FIXED - NEXTRELEASE. I dont intend to
make another release for a few weeks, at least. If you would like to check out
the fixed version, please look in the git repository for mock.
