Might help if you attached the file you promised to :)

Please show the contents of /var/log/audit/audit.log after selinux prevents ybin
from working.

# setenforce 1; setenforce 0

The error I got was:

/sbin/ybin: line 818: /bin/mount: Permission denied

The generated lines in audit.log:

type=SELINUX_ERR msg=audit(1212433789.890:30): security_compute_sid:  invalid
