[gentoo-embedded] qmerge and friend

[Martin Gysel]

Hi

I tied to use qmerge on my 'embedded' system (well for the moment it
runs from a usb stick...). I don't have the portage tree there nor any
profile. Unfortunately qmerge exits with:
 merge: chdir(portage) failed: No such file or directory
then I set some more variabls in make.conf like PORTAGE_TMPDIR etc. but
there's still some 'info' missing.
what variables do I have to set to have it run?

the profile is necessary to convey fundamental information such as ARCH and 
ACCEPT_KEYWORDS.  and to a lesser degree, the system packages and default USE 
flags.  without a profile, you need to manually set all of those.

i guess we could tweak the qmerge code to not walk the profile if people 
provide ARCH and such themselves ...

Is it sufficient to "fake" the profile by simply having a profile path?
 Everything else defined in make.conf?

If not, what might be the minimal set of files in profile required? (I
guess they could mostly be empty?)

qmerge only ever required a minimal /etc/make.conf ; What Mike points
out is we can probably accept it from the env also.

I think that would be a good idea (less 'unneeded' files on the
target...). maybe combined with a script which walks through the profile
tree extracting all the necessary parameters and putting them in
make.conf...
