Re: [Vserver] Gentoo and hashified files
Oliver, Thank you very much for your description. It sounds highly interesting, and I may try it out when I have the time. Thanks!

Its a bit tricky - I will sketch the setup for you: I have a template /vservers/template - that is a full blown gentoo installation for vservers. When I do updates, I do them by chroot'ing to this dir - NOT by entering a vserver! This way the portage and the dependency database (stored in /var/) get updated. In the vserver guests fstab, I mount the "per guest" partition to /disk and overlay some bind-mounts for /var and some of the /etc directories (not the whole one!). For easy setups its also ok to make symlinks from /etc to the var partition The only thing you must take care of, are updates that change the config-files syntax. It should be obious that files on the per-guest config system (the cut-out parts of /etc and perhaps things in /var) are not updated. I use this setup for Webservers mainly, they are nearly equal so I just have a differing config for /etc/apache2, all network and hostname stuff ist done from outside.

Re: [Vserver] Gentoo and hashified files
Thank you David and Oliver for your replies. I am glad to see there are other using Gentoo with vserver happily, but it's disappointing that noone seems to be using vhashify. That's would be nice to have since I plan on having up to 60 vhosts. Oliver: I am somewhat amazed that your setup works. I would think Portage would get very upset, or at least confused, when packages that aren't marked as updated are, dependencies should be broken etc. But two years running is quite stable. Is it just /var and parts of /etc that are externally mounted, while /usr, /lib etc. are all shared?

Re: [Vserver] Gentoo and hashified files
This might be offtopic but perhaps useful. I have multiple guests that share the same root directly. All configuration and runtime relevant dirs (var and parts of etc( are mounted from a per guest partition. Works with no hasle here for over 2 years now Oliver -- Diese Nachricht wurde digital unterschrieben oliwel's public key: http://www.oliwel.de/oliwel.crt Basiszertifikat: http://www.ldv.ei.tum.de/page72 ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
Re: [Vserver] Gentoo and hashified files
I'll have to take a look at mine. I have a server running Gentoo with about 4 vservers on it for mail, ftp, dns, and web. Works like a champ, so I never really mess with it much. I didn't go down the vunify/vhashify path when I set this one up, so no experience to report. I used the defaults in make.conf set my catalyst build script.

Re: [Vserver] Gentoo and hashified files
Noone? That's disappointing. Then what would be a good choice as an alternative to Gentoo (the only distribution I have experience with) when using VServer in a production environment?
