Could the remount be done in that other service?

General approach when only part of a job requires root:

1.  Set the remount program permissions to
    -r-sr-xr--  root  foo
    (i.e. setuid root, executable only by group foo).
    The program must be an executable binary, not a script.

2.  Ensure that the service which will run the remounter
    -- and only that service -- runs as group "foo".
