Description Alejandro 2011-09-14 10:17:44 UTC
SELinux is preventing systemd-readahe from 'create' accesses on the archivo .readahead.new.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that systemd-readahe should be allowed create access on the .readahead.new file 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 systemd-readahe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

This looks like .readahead.new is being created in a users homedir?  Either you have a messed up labeled system or something is very wrong?

Comment 2 Alejandro 2011-09-15 17:31:22 UTC
Something was really wrong with SELinux, as I had to disable it in order to be able to boot the computer normally. However, after testing Fedora for a few days I decided to go back to Archlinux so if nobody has this problem then the culprit must be my system (working flawlessly with Arch, go figure!)
