Thanks very much. It was listed as a requirement for kde4, and is still listed as required for kde5 according to
this FreeBSD handbook entry and
this KDE.org setup guide. I've seen other authoritative sources saying that it was still required. On the other hand,
this FreeBSD article says that FreeBSD software can use
sysctl
as a workaround for it, but the same article also suggests that some applications may still require it.
I would personally like to stop mounting
/proc, but until it's officially deprecated and removed from the requirements, I'll continue to configure it for my kde5 setups. I've already eliminated
hald
, but its deprecation seems to be a little better documented, and I've found several ways of working around it where auto-mounting is concerned--
hald
can still be used for automounting, and, as far as I know, it's still required for webcam operation to work properly. I don't need or use
webcamd
, so I don't believe I need
hald
either.
