This is something I wanted to support on 0.6 but ran out of time, and has been simmering in the back of my mind for a while. This thread make me think a bit about it, and made me realise that it is currently probably pretty dangerous. Here is what is dangerous: we need /library mounted very early, and always mounted. Else, data corruption and general messiness looms. What counts on /library ? In order of seriousness... - PostgreSQL has it's DB there. And if its datadir is not there, the init script will assume it's first boot and initialise the directory. - Moodle -- needs Pg, if it finds an empty DB it will initialise one. - idmgr -- registration creates a userdir there. If it's not mounted, it will create userdirs under the directory used for the mountpoint. (Or maybe a soft failure) - backups -- probably a soft failure if /library isn't there - apache, xs-activation -- soft failures due to missing data To handle this in a less risky manner, we'd need the main services to only run if the "real" library is there. With that in place, the udev trick would need to extend to re-starting some services, or the services would need a "supervisor" script "listening" for the mount via inotify. Which is a lot of garbled talk to mean: it'll be fine for a test server. Where we need this to be bulletproof and failsafe, lots of work to do... cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
