Hi Soren

I discussed your questions re what LTS means with Sage (upstream
project founder).  Exactly how long 'long term' is is still being
defined based on user/distro/other project requirements but we did
discuss the following...

Each LTS release goes through a period of aggressive bug fix
backporting; this does tail off BUT if users do encounter a bug then
it would still be addressed upstream given sufficient criticality.

Ceph are moving to a 3 month release cadence - not every Ceph release
will be an LTS release but the LTS releases are expected to line up
with distro releases.

If this does happen we would just stick with the most recent LTS
release available.

Agreed - I will work on this.  Would basic smoke testing be sufficient
for a provisional MRE?
