Hm. We are using hard-coded paths since we avoid using a shell for
subprocess invocation. We're going to change to a PATH-honoring setup
in one of the next versions, but we're going to set our own PATH on
startup to avoid privilege escalation issues. Most probably, the PATH
will be /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin,
so you'd really need to divert /usr/bin/chfn away to have
/usr/local/bin/chfn used.

Greetings
Marc
