Hello,
I recently got me a Raspberry Pi4b to use as a PiHole [1]. As a first
step I put user-space Gentoo (i.e. aarch64 stage3) on it and now I am
trying to set up my desktop to cross-compile binary packages for the PI,
to keep the Pi up-to-date in reasonable computing time.
I've built the cross toolchain with 'crossdev --taget
aarch64-unknown-linux-gnu' per wiki [2]. I've selected a 23.0-split-usr
profile on the Pi since this is the one supported by the crossdev (or so
I understood from the error message when I tried with the non-split-usr
profile on the desktop).
The crossdev environment on the desktop knows nothing about the packages
installed on the Pi, so I copied /var/db/pkg from Pi to
/usr/aarch64-unknown-linux-gnu/var/db/pkg on the desktop. I ran emerge
--sync on the Pi and on the desktop approximatively at the same time.
==== Now If I try a @system update on the Pi I get: ====
pihole ~ # emerge -uDvN --ask @system
These are the packages that would be merged, in order:
Calculating dependencies... done!

==== What am I missing to make the desktop use the same list of packages
to be upgraded as the Pi? ====
