Which should be fine from the script's point of view as long as
$remote_fs is in the "Required-Start" header (i.e. /usr is guaranteed to
be mounted).

That seems to be unlikely, but you could add a line with "echo $PATH" to
the script to find out what PATH actually is.

PATH is set directly by init.  If I read the source code correctly,
sysvinit sets it to "/sbin:/usr/sbin:/bin:/usr/bin" while systemd uses
