They'd become 1.2+LOCALBUILDREV+gitrfoo and 1.3+LOCALBUILDREV+gitrfoo.

SRCPV solves one particular set of bugs where local build revisions were
only injected into revisions part of the time. This change makes things
more consistent and predicable in that its always injected.

Nobody has ever written code to share the bitbake persistent data
between machines. It shouldn't be that hard with some kind of database
server but nobody has done it.

It doesn't really change the position for Angstrom as I understand it
though as you don't (can't) use these packages now due to the multiple
build servers and that position hasn't changed :/.

Cheers,
