This permissions problem just cost me over $44 (australian dollars).

I upgraded pppd on the dialin machine at work on Friday night.  Forgot to
change the permissions on pppd to make it owned by root.ppp, perms=1750. 

When the line dropped out from my home machine to my work machine at 5am
the next morning, my home system automatically dialed in to re-establish
the link.  Logged in OK, ran pppd.  The connection dropped again because
it didn't have the right perms.  My system then proceeded to call every
2 minutes, until I got home and stopped it at about 11am.

A local call here in Australia costs 25 cents.

An expensive mistake.

The postinst for ppp package SHOULD ask if permissions on /usr/sbin/pppd
should be changed.
