[gentoo-user] question/feature request: First fetch, then compile...

[meino.cramer@gmx.de]

Hi,

On my embedded systems (beaglebone black, 2 x Arietta G25) I installed
Gentoo (of course!:).
Since these systems and especially the Ariettas are not as fast as a
PC the greater update, which additionally includes C++ sources to
compile takes time (read: hours) to finish. Often I run this over
night.

Since my PC do the forwarding of requests to the internet, it has to
run the whole time also.

To circumvent this I access the embedded systems via abduco/dvtm, so
I can log out while the process keeps running.

The current (shorted decription) workflow is

eix-sync
emerge ... -f (fetching all items, so the connection to the internet is
               no longer needed)
emerge ...    (starting the compilation, logout and shutdown the PC)


This includes "Calculating dependencies" twice of the same set of
data, which also takes a longer time. This is -- technically -- not
needed.

Is it possible, to do ONE call to emerge, which asks (according
to option -a, if set ) and given a yes first fetches ALL necessary
files and data and compiles then everything?

This would save one "Calculating dependencies" and also reduces writes
to the flash memory.

Is it currently possible somehow and if not: I would like to have it
included as new feature into an upcoming release of emerge?!?!

Thanks a lot in advance! 8)
Best regards,
Meino
