ntpdate in fc17 template

It seems like we can use the following program (need to be installed on fc17 via 'yum install ntpdate'):

/usr/libexec/ntpdate-wrapper

So, solving this ticket requires two things:

1. Adding ntpdate to the list of packages
2. Modifying qvm-sync-clock to call ntpdate-wrapper instead of initd.d/ntpdate

Regarding #2 -- do we want to fall back to calling init.d/ntpdate in case there was not ntpdate-wrapper, or just assume the clockvm always runs on fc17?

I think we should have fallback. Perhaps (additional) wrapper in /usr/lib/qubes/, or implement it as qrexec service (this way we can inhibit hardcoded path in dom0).

Yes, I like the idea of having qubes.SyncNtpClock service.

Note that this uses new qubes RPC calling method (with path to multiplexer given by VM agent, not dom0). But other services still uses legacy method (will switch it later, to not break update - first VM must be updated).
