FIX: under SLC5 we do not add the SELinux context to /etc/fstab since AUFS does not handle this correctly in this version of the kernel -.-
MINOR HACK: try out if the mount, remount, unmount cycle works as expected

FIX: Repo Creation under SLC5

SLC5 has SELinux enabled but is very permissive. Therefore we do not need to add a context=... argument to /etc/fstab. Additionally the aufs version for the SLC5 kernel does not handle this parameter correctly, and fails to mount.
