Hi,
i don't know all the (local) history of this, but we have a daily
process which untars files/directories. this is done over an
existring tree. We've longed used an option to first remove files
that already exist before replacing them. i believe this was done
using a local modification of the code. Anyhow, we recently upgraded
to a more recent tar, and started using --unlink-first.
The big problem with this is that --unlink-first also tried to remove
directories, which in our case is almost never possible. While these
errors are not fatal, they cause undesired/undesirable errors messages
as well as a non zero return code.
The file attached adds a --unlink-first-nodir option which behaves the
same as --unlink-first, except that directories are left alone.
i'd appreciate this being considered for inclusion in the next release.
Thanks,
Christophe
