[ptxdist] [PATCH] fstab: don't explicitly mount debugfs

[Uwe Kleine-König]

If the kernel in use doesn't support it having an explicit entry results
in a failure.

On systems with systemd it is mounted anyways by
/lib/systemd/system/sys-kernel-debug.mount iff DEBUG_FS is enabled in
the kernel.

I don't mind either way, but this does not fail at boot, right? It has
'noauto' in the mount options.
