Yes, I know I'm too late now ;)
We were way behind with our oe merges back then, and only recently I started 
to get back uptodate again. So I didn't even realise the impact it would 
have for us untill now.

But if you then decide to remove BB_GIT_CLONE_FOR_SRCREV again because you 
no longer need it, and somebody starts a clean build, the LOCALCOUNT would 
start at 0 again I guess.
So the versioning isn't consistent anyway when toggling 
BB_GIT_CLONE_FOR_SRCREV.

Yes, but only if you stick to the same buildserver, and as soon as the hdd 
crashes for instance and you have to start with a clean build, everybody is 
in trouble.
So personally, I would never even want to use SRCPV, unless it's for 
AUTOREV.

Would it be an idea to be able to only have BB_GIT_CLONE_FOR_SRCREV for 
those packages which have SRCREV = ${AUTOREV}?
