[gentoo-dev] PACKAGE_OVERLAY and arch /usr/portage/packages ideas

[Philippe Trottier]

That was sent to -core I should not send emails that early in the morning...
basically this works nice for me and it could be kept in mind for future 
portage...

=======================
Hello,

Here is one thing I do and suggest...

PORTDIR_OVERLAY="${PORTDIR}/local"

as default and --exclude it from rsync

then add a stamp to the binary packages... or the portage directory like
PKGDIR="${PORTDIR}/packages-ppc-2004.2

My make.conf looks like this(see under) and it works fine to deploy a 
lot of machines in a short time with my own ebuilds... also works for 
the other arch on the same network by changing few variables. So it 
could be nice to have these features in place in an easy to export 
fashion, I also export distfiles since there is no need to replicate all 
the files on all the machines. I use mainly nfs...

/usr/portage rsync on all the machines from another local machine.
/usr/portage/local exported to all platforms (ro)
/usr/portage/distfiles exported to all machines (rw)
/usr/portage/packages-arch-release exported to specific arch and 
releases(rw or ro)

rsync exclude packages* local distfiles

That would allow us to be taken more as a tune once, deploy everywhere 
distribution, also allowing a real good use of distcc, preventing the 
abuse of rsync mirrors (emerge gentoo-rsync-mirror), prevent abuse of 
package fetching, consistent deployment, specific ebuild for location 
and more than I can think of ...

Yours,
Phil
