[ale] /tmp set to read-only on boot (need help)

[Ryan Fish]

I've never received any form of diagnostic message when issuing "mount -a"
at any time before but I guess you could be right (I honestly do not know).
I have always just used that cmd to force NFS mounts if they failed to start
properly.

mount -a causes a mount to be issued for each filesystem listed /etc/fstab
so
if a filesystem is already mounted you should expect a diagnostic message.

That's normal - ignore it or be more selective in what you mount.
