That's because there needs to be a little more tweaking done with
respect to using the generated metalog with mtree, because the metalog
is not a complete mtree spec file:
- you need to remove the prefix (as you've worked out)
- you need to prepend the contents of /usr/src/etc/mtree/NetBSD.dist
to the metalog before calling mtree, so that directories
referenced in the metalog exist in t
We're still tweaking how this stuff works. For example, the hlink
entries (hard link) generated by install aren't yet understood by
mtree and makefs; I'm working on this.
