[pkg-ntp-maintainers] Bug#352610: Please create a udeb for ntpdate

[Rick Thomas]

NTP is something I know a bit about.

Yeah, ntpdate  will do the job, and it's a good bit smaller than the  
full ntp-simple package.
The alternative you were thinking of *may* be "chrony".
Both implement enough of the network time protocol (NTP) to do what  
you want.

However, keep in mind that NTP, by it's very nature, needs access to  
a network time server.  The operative word here is "network".  If you  
don't have access to the global internet, and you don't have an NTP  
server on your local network (or you're doing an install without any  
network connection at all for some reason) both ntpdate and chrony  
will fail.  You need to think hard about what you want to do under  
those circumstances.  Is it acceptable to have the d-i ask for the  
address of an NTP server at the same time as it's asking for other  
network parameters?  For what it's worth, some DHCP servers will  
allow you the option to ask for the address of a preferred NTP  
server.  But if you use this option, you need to think about what to  
do if it fails.

Doing something that will work in the easy cases is pretty straight- 
forward.
Getting the corner cases right is non-trivial.
