I'm not sure libarchive is at fault, it seems to be a bug/limitation
in the way install handles links with -M. For regular installs we
install -l h <prog> <link>
and the link then has the same permissions via the existing inode.
With -M install produces a metalog containing
./<link> type=file mode=0755 size=0
(i.e., permissions not explicitly set) and we end up with two entries
in the metalog referencing two names for the same inode, but with
If we passed in the mode when invoking install for a hardlink we
should have the expected permissions, regardless of sorting:
# install -M METALOG -m4554 -l h <prog> <link>
./<link> type=file mode=04554 size=0
On a positive note there are only a few Makefiles with LINKS as well
as BINOWN, BINMODE, or BINGRP. As far as I can tell:
and of these shutdown is the only one that has a link that's not
already in alpha order.
