OpenBSD find does not have -printf which is used in /etc/etckeeper/commit.d/50vcs-commit to figure out who is running the command:

# uname -a
OpenBSD myhost 6.9 GENERIC.MP#473 amd64
# etckeeper commit
find: -printf: unknown option

I replaced USER="$(find "$TTY" -printf "%u")" with USER=dunno as this makes it work.

OpenBSD has perl in its base so:

perl -MFile::stat -E "my \$st = stat(\"$TTY\"); say( (getpwuid(\$st->uid))[0] )";


perl -MFile::stat -E "my \$st = stat(qq{$TTY}); say( (getpwuid(\$st->uid))[0] )";

would work.
