FWIW:
$>>grep PORTDIR\\\|DISTDIR /etc/portage/make/fs
PORTDIR=/p
PORTDIR_OVERLAY=/l/p
DISTDIR=${PORTDIR}/src
$>>grep exclude /etc/portage/make/net$>>cat /etc/portage/make/
rsync.exclude
# / on the left anchors (like regex ^), / on the right indicates dirs only
/layman/
/src/
/use.defaults
PORTAGE_RSYNC_EXTRA_OPTS="--exclude-from='/etc/portage/make/
rsync.exclude'"
$>>cat /etc/portage/make/rsync.exclude
# / on the left anchors (like regex ^), / on the right indicates dirs only
/layman/
/src/
/use.defaults
------------------------------------------
(/etc/portage/make/fs and the corresponding net file are sourced by
/etc/portage/make/master, which in turn is sourced by /etc/make.conf, so
those settings appear in portage, even tho they're actually in files in a
particular subdir of /etc/portage.)
So I have PORTDIR set to /p, with the layman and src subdirs in it, and
portage's rsync command set to exclude those subdirs.
FWIW, /usr/portage is a symlink to /p, just in case.
As Kent said, if that arrangement gets nuked despite my rsync --exclude
settings, the person responsible certainly won't be particularly popular
here (tho nothing irreplaceable would be lost, here, I'd simply have to
adjust things and try again).
Fortunately, our portage devs appear to be a bit more sane than to try
that and Zac at least isn't even proposing it. His proposal is to simply
change the default location for new users, which is fine by me. =:^)
