Some of us old foggies remember a time long before all these new fangled journals and cow filesystems. The days of ffs, ext, fat12, dfs, adfs...... I'm not even that old, as ive only used unix on IP stacks some of the boys and girls in here will remember decnet and having to flip multiple switches to boot systems, and card readers. There may even be the odd abacus user as well!!! On 21 October 2015 at 20:38, Brandon J.
