Hi
Follow-up question to the backup thingy.
Is there an easy way to share Portage's database between multiple
virtual machines?
Optimally, I would emerge --sync and the results would land in a
filesystem that I'd share between VMs, so I don't have to do emerge
--sync in each and all of them. The filesystem could perhaps be
readonly to the virtual machines, except for the one doing the --sync
of course.
I share /usr/portage across several machines as an nfs mount. 'emerge
--sync' is done on only one machine.
Until recently, 'emerge --metadata' was still needed on the other
machines, but thanks to the metadata_overlay database, this is no longer
necessary. And most emerge-related activities are much, much faster.
[To use the new database module, with portage-2.1, put
in /etc/portage/modules:
portdbapi.auxdbmodule = cache.metadata_overlay.database
in /etc/make.conf:
FEATURE=-metadata-transfer
and remove /var/cache/edb/dep/\${PORTDIR} ]
To have distfiles safely shared across the many machines, you need
FEATURES=distlocks and you'll need to relocate (or mount separately)
${DISTDIR} if ${PORTDIR} is read-only.
Also, I think you're getting into questions that should be on -user. ;)

The filesystem could perhaps be readonly to the virtual machines, except for the one doing the --sync of course. (Currently, I run emerge --sync in all virtual machines.) I current use NFS to share my portage tree at home. All you need is to store the portage tree on one machine. I would suggest the actual machine the virtual machines run on, rather than the virtual machines themselves, but you really can put them anywhere. You want the tree to be writable, too, so that you can sync from any machine and also because of distfiles. -- Chris Gianelloni Release Engineering - Strategic Lead x86 Architecture Team Games - Developer Gentoo Linux signature.asc Description: This is a digitally signed message part

Please Please Please read the docs before using metadata_overlay; there
are some stipulations you need to follow when turning it on,
specifically you cannot edit eclasses. Otherwise, let it loose ;)
