Can a slave hd hold a fresh new clean Linux OS, same as the primary's OS.. and somehow be used to repair and/or replace a corrupted primary hd's OS.. like how Windows OS's have a restore system..?
Since most Linux OS's are free ISO image downloads, and the quarter million peripheral softwares are all free too.. do you suppose one could copy the ISO to the slave, along with a downloads manager set of updates, and the files backup, to somehow all be applied to reinstall the primary's OS from the slave after DBAN erasing the primary..?
