[gentoo-alt] prefix repo_name gentoo_prefix vs. gentoo

[Michael Weiser]

Hi guys,

for years I've sporadically seen messages such as

!!! Section 'gentoo' in repos.conf has name different from repository name 'gentoo_prefix' set inside repository

when calling emerge --sync et.al. without any negative effects. Today it
finally caused me grief, because crossdev's heuristic for finding the
first overlay selected $EPREFIX/usr/portage instead of
$PREFIX/usr/local/portage.

So I looked into what it does: It calls portageq
repositories_configuration $EPREFIX and on my system that gives:

# portageq repositories_configuration /usr/local/gentoo/
!!! Section 'gentoo' in repos.conf has name different from repository name 'gentoo_prefix' set inside repository
[DEFAULT]
auto-sync = yes
main-repo = gentoo

[gentoo]
aliases = gentoo
auto-sync = yes
location = /usr/local/gentoo/usr/portage
masters = 
priority = -1000

[gentoo_prefix]
aliases = gentoo
auto-sync = yes
location = /usr/local/gentoo/usr/portage
masters = 
priority = -1000

[local]
auto-sync = yes
location = /usr/local/gentoo/usr/local/portage
masters = gentoo_prefix
priority = 0

Mhmm. I do not have any repos.conf in $EPREFIX/etc/portage. So as a quick hack
I went and replaced gentoo_prefix by gentoo in $PORTDIR/metatada/layout.conf,
$PORTDIR/profiles/metadata, $EPREFIX/usr/share/portage/config/repos.conf and
$PORTAGE_OVERLAY/metadata/layout.conf (masters).

That got rid of above warning, portageq now shows

# portageq repositories_configuration /usr/local/gentoo
[DEFAULT]
auto-sync = yes
main-repo = gentoo

[gentoo]
aliases = gentoo
auto-sync = yes
location = /usr/local/gentoo/usr/portage
masters = 
priority = -1000
sync-type = rsync
sync-uri = rsync://rsync.prefix.bitzolder.nl/gentoo-portage-prefix
sync-rsync-extra-opts = None

[local]
auto-sync = yes
location = /usr/local/gentoo/usr/local/portage
masters = gentoo
priority = 0

... and crossdev correctly selects $EPREFIX/usr/local/portage as first overlay.

Is there something wrong with my setup or can someone else seeing this as well?

Thanks,
