Hm, netstat should be expected to require libnetgraph.so.4 - at least
on 12.1-RELEASE:
$ ldd /usr/bin/netstat
/usr/bin/netstat:
libkvm.so.7 => /lib/libkvm.so.7 (0x80026b000)
libmemstat.so.3 => /usr/lib/libmemstat.so.3 (0x80027e000)
libxo.so.0 => /lib/libxo.so.0 (0x800284000)
libutil.so.9 => /lib/libutil.so.9 (0x8002a4000)
libnetgraph.so.4 => /usr/lib/libnetgraph.so.4 (0x8002bb000)
libc.so.7 => /lib/libc.so.7 (0x8002c2000)
libelf.so.2 => /lib/libelf.so.2 (0x8006bb000)
I.e. the problem is presumably not with netstat, but that
/usr/lib/libnetgraph.so.4 doesn't actually exist on the specific VM. I
don't know whether freebsd-update can be expected to re-create files
that have "gone missing" other than due to changes between FreeBSD
versions, but I wouldn't think so (AFAIK /usr/lib/libnetgraph.so.4 has
been part of the release since at least 10.3-RELEASE - probably much
longer, it's just the oldest version I have around).
Does it work to run netstat outside of cron?
