Please forgive me if the answer is obvious, but why is dpkg-divert
checking for ENOENT _in addition to_ checking for a successful lstat()?
It seems to me that all possible failure modes of lstat() should have the
same significance in dpkg-divert. It also seems that update-alternatives
is checking for ENOENT after the fact where -e or -l before the fact would
more correctly and portably fulfill the intention.
I'm not arguing for/against adding Errno to perl-5.005-base, nor am
I criticizing the dpkg team's code; I'd just like to understand if there
are deeper issues I'm missing here.
