I don't think that is really needed if you are careful with the options,
for example, if you use gnu-cpio with "-H odc", it should be portable to
just about anything, and this would be the same as what tomsrtbt would
create from its pax or cpio. You will want to run a test anyway. I would
feel comfortable backing up with gnu-cpio and restoring with tomsrtbt-pax.
