The earlier cycles might also be 10 weeks, which adds more uncertainty. [...] > > > - How long does Greg's LTS last?

Seems > like we are not getting a lot from sticking with 4.4 then? Sorry, either I mixed up maintainers there or I meant to say that we would have 15 months *after* January 2017. Greg typically maintains a 'longterm' branch for about 27 months: 2.6.32: 2009-12 .. 2012-03 (then transferred to Willy Tarreau) 3.0: 2011-07 .. 2013-10 3.4: 2012-05 .. 2014-08 (then transferred to Zefan Li) So we can expect: 4.4: 2016-01 .. 2018-04 > From what I can gather so far: > > * We are looking at moving the freeze at least 2 months if we want > Linux 4.10. > - At +2 months, Linux 4.10 would be just before the "deep freeze" > (Assuming a 10 week release cycle for Linux). > > * If we stick with 4.4, the Debian Linux maintainers receives > practically no advantage from Greg's LTS effort. No, we would benefit from that but this is very early to freeze the kernel and we would need to do a lot of work on backporting hardware support.
