Er, Mutlicks had a requirement for stable storage too, back in the prehistory of Unix... One's files were migrated automagically to a storge medium after creation or change. Perhaps someone old enough could comment on this? --dave [One of the requirements of a timesharing service is that one can feed confident in keeping one's **only** copy of data online: it is a system requirement to checkpoint/journal/backup at fairly fine intervals to prevent losses of significant work.
