But librefuse and libpuffs live in /usr/lib, so this doesn't work if /sbin is available but /usr is not, which is usually why we put things in /sbin.

Yes, please!

Either mount_qemufwcfg should live in /usr/sbin or we need to move libpuffs and librefuse into /lib, which is not great.

(See also PR bin/58638: mount_qemufwcfg(8): usage is confusing (https://gnats.NetBSD.org/58638), which notes that mount_qemufwcfg(8) is incompatible with mount(8).  Making it compatible requires keeping mount_qemufwcfg in /sbin.)
