Just a reminder: complaints on a blog don’t get bugs fixed. File proper bugs or e-mail bugs@ so people can actually fix these properly (or as with the pf rules variable problem, get it documented in the upgrade FAQ so others can be made aware of them).
I’ve been using OpenBSD since way back at release 2.3 in 1998
I would expect someone, who uses the OS for such a long time and has complaints about fairly rare use cases (pf.conf.local, sudo config file across machines, tcpwrapers) to be running at least one machine as -current.
That way he would both be able to provide feedback, know about the changes and maybe prevent some from happening with good reasoning.
