Package: ntp
Version: 1:4.2.6.p2+dfsg-1+b1
Severity: normal
*** Please type your report below this line ***
Hello,
I found that ntp may not startup / run correct in Debian 6. Using ntpq
the local clock is shown as not used.

I read the changelog and found that ntp may be started by ifup
so I thought it may be caused because the loopback address may
not be set up at this moment. So I restarted ntp and now it looks
like this:
ntpq> pe

But then ... after a while ... I looked again.

The local clock seems to be gone as soon ntp switches zu a real
time server ... or such like. I verified this on another Deb 6 system.
For me this looks like a real bug.
Best regards,
Stephan
