Subject: Add FAKEROOTNOENV variable
X-Git-Tag: rev_ivi_2015_02_04~19895
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e73bf727729b6ab16f3a6426d8396a8899569524;p=scm%2Fbb%2Ftizen-distro.git

Add FAKEROOTNOENV variable

Add a FAKEROOTNOENV which does the opposite of the FAKEROOTENV variable
and is data loaded into the environment for tasks without the fakeroot
flag.

The intent here is to provide a way to control the environment when we
aren't needing fakeroot context which allows us to unload the preload
from memory entirely and gain a valuable speedup.

I'm not 100% happy with needing this at the bitbake level, particularly
with the cache hit but it does give a valuable speedup.

(Bitbake rev: 05c29ab0b2ad3c521414cabb6a92bca15c6e919c)
