[net.wanted] restor which organizes files

pn (02/01/83)

I have the impression that the straight V7 restor brings things in exactly
as they were, and that it is possible to write one which trys to make the
blocks in a file contigious. is this true and does anyone have one? thanks.

Actually, a dump-mkfs-(icheck -s)-restor reorganizes the layout of data
blocks within a file system to their "optimal" value.  That is, during a
mkfs (or "icheck -s"), the free list is sorted to minimize latency between
successive reads (as delivered, for an RP03--it might be necessary to tweak
the parameters for other disk hardware.)

So, the actual block addresses in which files reside will not remain the
same between a full dump/mkfs/restor.
