AFAIK That has always been the case. I was using it to hardcode the
cpuinfo and cmdline shown in honeypots.

Yep, I was running this instance outside of the chroot for now (because
of the libcap lib dependency) and not where the honeypot.pl expected it.
Also, the path was wrong chroot/proc/proc, 'lsof' showed me what I was
doing wrong, but it still isn't working as expected - more on this
later.

BTW, I copied /lib/libnss* to the chroot but the pcap interface does not
come up:
ifconfig eth1 0.0.0.0 promisc up
SIOCSIFFLAGS: No such device
SIOCSIFFLAGS: No such device
So something else must be missing... Any ideas?
