FC5 isn't giving me this problem using 4.2.4p0-1.fc6. I do have the 2 local 
clock lines (server, and fudge) uncommented, and when I boot the machine with 
no Internet connection, then after connecting to the Internet (dialup) , I 
run ntpq> pe, it shows local as a system peer, and 3 servers from 
fedora.pool.ntp.org dynamic. It does take ages before one of the servers is 
set as system peer, but it's working.

On FC2 using 4.2.0-7, I am using 3 specific stratum2 servers, rather than a 
pool. Could it be that because I only have 3 specific servers, that they are 
being tried once while there is no initial Internet connection on bootup, are 
failing to be found, and ntpd is not trying them again.  I presume a server 
pool has many available servers, so if I have a server pool in /etc/ntp.conf, 
does ntpd just keep on trying to get a response in this case, like it tries 
the pool, doesn't get a response, tries again, no response, tries again, and 
so on, by which time I have made the Internet connection, and it's still 
trying to find a pool server, and now with an active Internet connection it 
gets a response, and sets up 3 available Internet servers?

As I'm having problems installing 4.2.4p0 from the tarball on FC2, I think 
I'll try reinstalling 4.2.0-7, put a server pool in /etc/ntp.conf, and see 
just for hell of it, if it works.

All in a days work.
