Not the first time here but I hope I found something real this time:
# /usr/local/sbin/dhcpcd -d -N
chrooting as _dhcp to /var/empty
main: eloop_start: Not permitted in capability mode
# uname -a
FreeBSD xxx 11.4-RELEASE-p7 FreeBSD 11.4-RELEASE-p7 #0 r369258
Only can see that on 11.4 release and not on 12.2-STABLE.
PS: Wishing you luck and good health! Never give up!
Sorry, due to a lack of time I have reset the maintainer of this port back to ports@FreeBSD.org. Hopefully someone else is able to step in to help.
Resetting the assignee of this bug accordingly.
