Mike,
Thanks for the help here. This is the exact solution I was looking for.

It is possible for rancid to deal with the pager on netscreens. In my
infrastructure rancid has read only accounts on devices, so has no
ability to edit the console page, it gets on fine... admittedly I had to
hack the code a bit, as the build in read-only support was broken.
Problem and fix when originally discovered:

Paul Zimmerman took the trouble to tidy this up further, details at
bottom of email
There is no reason this method couldn't be used for read/write accounts.

That does not seem to be a very good fix. If another user happens to be
logged-in when rancid runs, the pager will be disabled AND if another
user re-enables the pager it will confuse nlogin, possibly causing it to
hang (thus more emails about problems collecting...).
A better fix, assuming this is still a global knob, is to deal with the
pager, if possible.
