Please add the 'dd' command to the installer shell and rescue mode. There have been several times when it would be really nice to be able to use dd to wipe a disk with zeros, copy disk blocks, etc.
Hmm, actually dd does exist in rescue mode. But while we're at it *pretty pretty please* add vi too. I can definately understand the inclusion of pico to make life easier for new users but ...
In the Fisher beta your system's directories are mounted under /mnt/sysimage, so you can run vi from there.
