:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that gdm-session-worker should be allowed read append access on the .xsession-errors <Unknown> by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep gdm-session-wor /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-02-01 09:22:25 UTC
You need to tell SELinux where your homedir is:

# semanage fcontext -a -t home_root_t "/export"
# semanage fcontext -a -e /home /export/home
# restorecon -R -v /export
