Setting up a local rsync mirror for a portage tree is fairly simple, you share the working tree at /usr/portage on a local server to the network and make sure the server is up-to-date before syncing other clients to it. This is documented in [1]. After setting up the mirror, you only need to sync-uri in /etc/portage/repos.conf on the other (local) clients. See portage(5)[2], section 'repos.conf' and make.conf(5)[3], section 'SYNC' for details on client configuration. Please *do* read those sections, as much of the information on the wiki regarding the SYNC variable is outdated. For sharing distfiles between hosts, a http server sharing the distfiles folder and prepending the server's uri to GENTOO_MIRRORS in make.conf[3] might be sufficient for your needs. If the installs are not homogenous, you can even set up http servers on all of them, and add all the other local hosts to GENTOO_MIRRORS. You might want to skim through the FEATURES section in make.conf(5)[3] for using local distfiles mirrors, as some of them can improve the usefulness of the mirror significantly. NFS is another possibility for both portage tree and distfiles and can reduce total disk space needs, but it incurs significant network latency which is especially noticeable for portage trees. I use it myself for virtual machines, but would not suggest it for use over a physical network. Also note that portage has PORTAGE_RO_DISTDIRS[3] as an alternative to GENTOO_MIRRORS for eg. read-only *mounted* network shares which may provide some extra flexibility. 1: https://wiki.gentoo.org/wiki/Project:Infrastructure/Rsync#Setting_up_your_own_local_rsync_mirror 2: https://dev.gentoo.org/~zmedico/portage/doc/man/portage.5.html 3: https://dev.gentoo.org/~zmedico/portage/doc/man/make.conf.5.html -- eroen
