Great timing as I recently got hit by the sudden and unwelcome appearance of /sbin/fsck_ext2fs on my systems.  I created https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249284 <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249284> to track this issue.

I believe that 1a) is the sanest and probably easiest to implement, or maybe we should add an option to fsck to specify additional paths too look at and update rc scripts to include /usr/local/sbin automatically.
