  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

[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.  That was interpreted as ``a few hours at
worst'' in the Multics requirements spec]
