This is actually conceptually very similar to what I've been meaning to set up. My scheme would be something like: 85% — command all Unix hosts to unmount NFS shares, shut down NAS, shut down non-critical appserver (this roughly triples runtime) 20% — shut down primary application server 10% — order shutdown of remaining connected workstations, keep network stack running as long as battery lasts But I simply haven't had the time and energy to get to it. -- Phil Stracchino Babylon Communications ph...@caerllewys.net p...@co.ordinate.org Landline: +1.603.293.8485 Mobile: +1.603.998.6958 _______________________________________________ Nut-upsuser mailing list Nut-upsuser@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
