FreeNAS Code

Extremely crude attempt to support upgrades.

eliminate some now-useless code.

Try /dev/cd0 if /dev/acd0 fails

Two minor tweaks to the installer to make it clearer that the commit dialog is your last chance to bail.

Cleanup templates

Erase both ends of the disk, and remove redundant erasing

o Add the disk size to the choices to install onto.
o Move the warning screen until AFTER the install disk choice screen
- in future versions we'll have an upgrade option there
o loop over install.sh: if it exists, the install is borked. The only sane
thing we can do is restart the install process.
o Simplify things somewhat.

Now that we've debugged things, we can ratched the verbosity down.

Code cleanup. Also, eliminate dialog boxes for shutdown and reboot. Move install process earlier in the rc boot script... maybe we could just replace it with what we have in install.sh, since it isn't doing much anymore.

Don't copy .svn files
