Oh, and under what OS were those files created?  RHEL-5 or F-14?


The files were created in rhel5 and /home there was mounted using the
context I posted before:

LABEL=/home             /home                   ext4    defaults,context=user_u:
object_r:user_home_t:s0        1 2

The avc denial was produced when reading the created files on F14.

Basically, what I did was:

1) I booted on rhel5, and updated my rhel5 RPM repo (createrepo+repoview).

2) I booted on F14 again and tried to use mock to create some rhel5 rpms
accessing the local repo updated on step 1.

3) I reset the context on F14, and mock could access the files normally.

I have two different users, with the same ID (500), in fedora 14 and rhel5,
and basically these users share some directories in /home used for keeping rpms,
and a few directories accessed by httpd, and kept in the home of the fedora user.
