If we find a way to allow PRINC in multiple bbappends for same .bb then
we can say that every .bbappend should use PRINC.

For record I'll include my discussion about PRINC with RP and kergoth:
10:47 < JaMa> RP__: is there any way to improve PRINC concept to allow multiple increments for same recipe while parsing multiple layers?
10:48 < RP__> JaMa: PRINC_append = ".1" ?
10:49 < JaMa> RP__: ie when meta-openmoko sets PRINC = "1" and meta-shr sets PRINC = "2" then if you're unlucky meta-openmoko is parsed later and bumping PRINC in meta-shr won't help
10:49 < RP__> JaMa: I wonder if you could do PRINC := "${PRINC + 1}"
10:50 < JaMa> and do we have default PRINC = 0 somewhere?
10:50 < RP__> JaMa: you might need to add that
10:50 < JaMa> ok, I'll try this, thanks
10:51 < JaMa> currently I'm moving PRINC only to meta-shr layer.. but that breaks stuff if someone is using any BSP layer from meta-smartphone..

14:53 < JaMa> RP__: btw that PRINC trick didn't work (int type didn't like expresion :/)
15:13 < RP__> JaMa: ah, try PRINC := "${int(PRINC) + 1}"
15:21 < JaMa> RP__: still ValueError: invalid literal for int() with base 10: '${int(PRINC) + 1}'
15:21 < JaMa> with added PRINC := 0 to bitbake.conf
15:22 < RP__> PRINC := "${int(d.getVar(PRINC)) + 1}" ? :/
15:22 < JaMa> whole log http://paste.pocoo.org/show/514437/
15:22  * RP__ was trying to be too clever I suspect
15:23 < JaMa> ValueError: invalid literal for int() with base 10: '${int(d.getVar(PRINC)) + 1}'
15:41 < kergoth> PRINC is unquoted there, so it tries to get a value for a key of None
16:24 < RP__> kergoth: right, trying to do too many things at once :/
16:24 < RP__> kergoth: any thoughts on that knotty change to add the footer?
17:05 < JaMa> kergoth: something like this? ValueError: invalid literal for int() with base 10: "${int(d.getVar('PRINC')) + 1}"

Maybe someone else has better idea?

Cheers,
