[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?)

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...

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