[gentoo-user] crossdev setup questions for distcc usage

[Walter Dnes]

Probably the first of many.  I emerged crossdev on my 64-bit PC.  When
I ran "crossdev -t --help", it wanted an overlay, and pointed me to
https://wiki.gentoo.org/wiki/Overlay/Local_overlay which led me to...

mkdir -p /usr/local/portage/{metadata,profiles}
echo 'netbook' > /usr/local/portage/profiles/repo_name
echo 'masters = gentoo' > /usr/local/portage/metadata/layout.conf
chown -R portage:portage /usr/local/portage
echo 'PORTDIR_OVERLAY="/usr/local/portage ${PORTDIR_OVERLAY}"' >> /etc/portage/make.conf

  I now have a line...

PORTDIR_OVERLAY="/usr/local/portage ${PORTDIR_OVERLAY}"

...in /etc/portage/make.conf wich leads to a few questions...

1) Given that I don't have PORTDIR_OVERLAY previously defined, can I
safely cut down that line to...
PORTDIR_OVERLAY="/usr/local/portage"

2) Does this imply that one can have multiple, space-separated,  overlays
PORTDIR_OVERLAY="/usr/local/portage /fu/bar /whatever/wherever"
