From the pull request pending, #31320:
On NetBSD, Salt currently defaults to using lsof(8) to determine which
minions are connected. It is however not always available, and even
then quite unreliable. I found that just like on FreeBSD, sockstat(1)
is a much safer alternative. Unfortunately its output is not exactly
the same on NetBSD, where the port delimiter is a dot character
instead. As a consequence I have decided to duplicate the relevant
function for NetBSD; let me know if I should try to re-use the code
supporting FreeBSD instead.
