Ah that makes sense, thanks.

I did read somewhere Mark said that the site reboot command does the ro stuff first, but other reboot commands do not. But I cannot remember exactly what it was and in any case I might have got that the wrong way round. Trouble is I cannot find that post again.

Anyone know what reboot does what?

Also, how can I at the remote end of an ftp link find out if the ro command worked (so I don't reboot while it's still rw)? Or if site reboot handles the ro then maybe I don't need to worry.
