To be honest I have a gist as to what you're saying but I think the =
build is suffering from shibboleth-itis. Meaning it's not serviceable =
unless you're intimately familiar with it=85
I *guess* that ITOOLS or maybe LOCAL_ITOOLS means programs needed to =
installworld/installkernel?
If so, then yes, makewhatis needs to be added to that.
As far as everything else written:
no idea what "CROSS_BUILD_TESTING" means, it's not documented anywhere I =
can see in the makefile.
I can't decode if there will be a target that "just works" for doing a =
cross-install, will there be? What will it be named and how will people =
invoke it?
Can we have cross-installworld and cross-installkernel targets please?
