the initial copy was too slow and would've taken weeks to finish, so i've
restarted it at a slightly faster rate.
the remaining problem is that some images have files with names longer than
100 characters, which standard tar(1) can't represent (the maximum length
is 155 characters for directory + 100 for filename).
given the wide availability of GNU tar, i don't see a problem outputting
GNU-format tar files instead of POSIX ones, but i can't find any
documentation on their format. at least, the tar info files are not very
enlightening. so, in the interests of useful image dumps, does anyone know
where this is documented? :-)
thanks,
kate.
