We've to tons of boxes that are a complete pain is the ass to install on via CD, this will save tons of time. Obviously, it would be better it we made one of these as part of the release build and put it on the ftp site, but this is a hugh step in the right direction. One minor nit, you might want to put a check that the user is root at the top of the script since that is a requirement. > P.S.: beer-ware license Are you going to be at BSDCan. :) -- Brooks > --=20 > Dario Freni (saturnero@freesbie.org) > FreeSBIE developer (http://www.freesbie.org) > GPG Public key at http://www.saturnero.net/saturnero.asc > #!/bin/sh >=20 > # You can set some variables here.
