Re: [Vserver] Hashify 'etch' trouble?

(that happened sometime in the beginning and only happened once. ;-) 2. upon upgrading or uninstall a package containing set[ug]id files, dpkg tries to unset the set[ug]id bit of the files (as a security precaution in case someone has hardlinked it and is keeping it around waiting for an exploit to be found in it). of course this fails as the hashified file cannot be modified, but even worse dpkg stumbles on making a mess without reporting an error/failure. i patched dpkg to not unset the file. another debian user patched vhashify to skip set[ug]id files, which is the more proper solution (i only patched dpkg because it was the easier solution having already found the problematic code in dpkg while debugging the problem). see the vserver mailing list archives for our patches. see bug http://bugs.debian.org/382760 for my dpkg bug report. those are the two problems i've ever found. a tip is to rehashify your vservers and prune your .hash directory after package updates. you can find a discussion on pruning scripts that i prompted on the mailing list sometime ago. Excellent, thankyou for that, those were exactly the sorts of problems I expected. I'd like to read the thread about pruning and the patches. The archive doesn't search well through google and has no inbuilt search. Any idea when the discussion was? I would prefer not to load anyones servers (and my HD) by downloading the lot.

What precautions would I need to take and what things can't I do inside these guest servers? I've been attending a Sun workshop yesterday (about Solaris 10, zones/containers, and HA). There's a number of close similiarities between HA on linux, and Linux paravirtualization technologies with Solaris zones/containers. Instead of vhashify (and symlinks) they're using loopback filesystem (LOFS) to minimize space for shared resources. I'm not sure why they chose that way, and didn't go for simple symlinks. well, first, we do not use symlinks for a good reason, and second, with the loopback filesystem, which is more like an overlay filesystem and/or --bind mount, the actual saving is not as good as with hardlinks ... best, Herbert -- Eugen* Leitl a href=http://leitl.org;leitl/a http://leitl.org __ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
