Description long 2012-04-30 16:06:26 UTC
SELinux is preventing /bin/systemd-tmpfiles from 'rmdir' accesses on the directory long.

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

If you believe that systemd-tmpfiles should be allowed rmdir access on the long directory 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-tmpfile /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-05-01 18:17:10 UTC
Did you mv your homedir to /tmp?

rm -rf /tmp/long

Should clean this up. We really do not want to allow systemd-tmpfiles to delete the contents of homedirs.

Comment 2 long 2012-05-01 20:11:38 UTC
That's what I'm confused about.  There is no /tmp/long (at least now, I have no idea if there was one there or not) and I can't tell from the audit message what it was trying to delete?

Comment 3 Daniel Walsh 2012-05-02 17:58:01 UTC
Well the only way I can imagine this happening would be if you have a directory like /home/long and you mv'd it to /tmp.  Then eventually systemd-tmpfiles see it as old and attempts to remove it.
