The following directories are good candidates to be shared between
Arch and Parabola mirrors:
- /pool/packages
- /pool/community
- /sources/packages
- /sources/community
The Parabola version of those direcories is in theory a strict subset
of the Arch version, though with different ftpdir-cleanup/db-cleanup
schedules, I suppose that could drift (especially as lag with Arch
Linux32 causes us to hang on to old arch=(any) packages for longer
than Arch does).
What I would suggest doing is hardlinking the files from the Arch copy
to the Parabola copy between the rsync for each:
# normal archlinux rsync goes here
archmirror=/path/to/archlinux
paramirror=/path/to/parabola
for d in {pool,sources}/{packages/community}; do
ln -f -t "$paramirror/$d" -- "$archmirror/$d"/*
done
# normal parabola rsync goes here

That one's a little tricker, because Arch Linux ARM doesn't use pools.
Parabola's /pool/alarm pulls from several different directories from
Arch Linux ARM. But again, *every* file there should able to be
shared with the Arch Linux ARM mirror.
