I say just print it to stdout on extract. The filenames (on disk)
will obviously always be homogenous on extract, but lar could have a
-C option like tar to relocate from cwd. Pathnames are always
straight from the larball.

Yeah, I guess the GMTA principle says this is the way to go.

The one-line-per-file is slightly problematic in that it makes
whitespace instead of : be reserved in filenames. :\ (Because the
filename needs to be there twice it's not possible to just put the
algo first and use the rest as filename.)

And I prefer "none" over "-" for no compression. Bikeshed though.

Sure, the manifest is certainly nice for scriptability. I'd like it
to be readable from stdin too. Maybe you can use some clever here
documents in buildrom then.
