In Ostro OS, building pack-world-dev-from-0.tar seems to lack all symlinks. Example: www/5080/Manifest.world-dev:L... 6285cea164786e1c0b2f9d3364eb4956b49970c6b62c0677154188b65e533c19 5080/lib/cpp As a result, "bundle-add world-dev" ends up with lots of "Path xxxx is missing on the file system". It proceeds by getting the individual file .tar for the missing entry, but that's slow. Beware that "bundle-add world-dev" is also slow (hours instead of seconds?) while downloading the pack-world-dev-from-0.tar because of https://github.com/clearlinux/swupd-client/issues/41 - but that's a different issue. Need to check whether lack of symlinks is a bug in meta-swupd or upstream.
Was a bug in my working branch of meta-swupd, fixed before merging to meta-swupd master 07ad71b789d73.
