Having some issues after a sysupgrade to the latest snapshot (of this writing) - OpenBSD 6.9-current (GENERIC.MP) #131.
Seems the base change to dhcpleased/resolvd has presented some issues. Pf does not start on boot as it claims my dhcp interface has no address, however after logging in I can load pf and almost resume normal operations. Apparently the interface does get an IP address, but the start of pf doesn't wait for it. Almost, because my supersedes, etc. in /etc/dhclient.conf are completely ignored. The only workaround I found was to disable resolvd so I could manually propagate /etc/resolv.conf without it being overwritten.
