Any specific reason for preferring it over the Debian ntp package? (I guess familiarity is often a biggie.)
I'm actually considerably _more_ familiar with NTP Project's ntpd, as it's the reference implmentation. The openntpd.org (OpenBSD Foundation) 'Portable OpenNTPD' alternative is intriguing as it aims to reduce the attack surface as a network daemon, which other things being equal is A Good Thing. Hence, I'm considering its relative merits at the moment and am undecided. I was about to say that it's still early days for the OpenBSD Foundation's codebase, but am surprised to note, upon checking, that this is wrong: The project was launched well over a decade ago, and I'm merely behind the news. ;-> (I believe I finally noticed it courtesy of an LWN.net article about recurring NTP Project ntpd security problems, and remedies via alternative implementations.)
And I personally feel much better running a real NTP implementation even on laptops.
After removing networking start from the startup scripts, in favour of manual networking start, for the few occasions when one is tethered?
In my use case, I pretty much always have either wireless ethernet or wired ethernet at startup.
