Subject: Apparent loss of files when doing `restore i'
Index: etc/restore/restore.c 4.2BSD
Description:
When using `restore i' or `restore x' on a multireel dump,
and using the recommended procedure of starting with the last
reel and working towards the first, restore will sometimes
give up after two or more reels, complaining that some list
of files are missing.
Repeat-By:
Find a dump spanning three or more reels and request restore
to extract files that reside on all three reels, plus THE file
that starts at the end of the next to last reel and continues
onto the last reel. Then load the reels from last to first. When
the next to last reel is loaded it will proceed to its end
and begin extracting the spanning file. Restore will demand
that the last reel be loaded (so that it can finish reading
the spanning file). After restore finishes extracting the
spanning file it should request that another reel be loaded.
Instead it will report that all requested files on the earlier
reels are missing.
