[gentoo-user] Local portage git mirror
Hello list, I have a small LAN, on which one box has little to do so I've set it up as a local git mirror. I use this box - the one I'm writing on now - as a compile server for a coule of other boxes, including the new git server, in which the clients export their portage tree over NFS v3 to this box. On those client boxes I've had to "chown -R portage:portage /usr/portage" to get the exporting via git to work; otherwise I get a read permission failure on .git/FETCH_HEAD. This is what I see on the compile host: $ ls -l /usr/portage/.git total 15M -rw-r--r-- 1 root root 267 May 7 10:59 config -rw-r--r-- 1 root root 73 May 7 10:49 description -rw-r--r-- 1 root root 104 Jun 4 09:49 FETCH_HEAD [...] But on the client boxes I now have this: $ ls -l /usr/portage/.git total 15M -rw-r--r-- 1 portage portage 277 May 7 11:33 config -rw-r--r-- 1 portage portage 73 May 7 11:31 description -rw-r--r-- 1 portage portage 104 Jun 4 10:24 FETCH_HEAD [...] I did try chowning to root:portage first, but I still got the permission error. Have I done something daft here? -- Regards, Peter.

[gentoo-user] Local portage git mirror
Hello list, Does anyone have some pointers to setting up a local portage mirror for git to serve? I'm looking at http://www.funtoo.org/Portage_Git_Mirror but some details are obscure to me. I hope I'm not going to have to roll my sleeves up and learn the whole of git; I just want to cut down the time my boxes take to sync via git - some of them have their portage trees nfs-mounted in chroots on my workstation and take anything up to 20 minutes to sync. One question comes up straight away: should the git-served repository be the host's own /usr/portage tree? And what cron task should I run to refresh the mirror? Any help would be gratefully received. (I can still read e-mails via web-mail even when KMail is playing up.) -- Regards Peter
