To the contrary, it does modify debuggerd in order to use its daemon behavior (START | STOP) and access rights for the proper mount options to provide global access to the USB drive.

Here's the full root log captured by SuperSU:

As you can see debuggerd is backed up to debuggerd.backup and the first 'echo' command clears debuggerd and writes the one-liner shebang.

The following 'echo' commands are appended, the script is given owner/perms, the 'system' is mounted RO and 'start debuggerd' executes the script.

Then file is then returned to it's initial state from the .backup

stop debuggerd
mount -o rw,remount /system /system
cat /system/bin/debuggerd.backup > /system/bin/debuggerd
chown root.shell /system/bin/debuggerd
chmod 755 /system/bin/debuggerd
mount -o ro,remount /system /system
start debuggerd
exit

The above is the 'mounting' process; it goes through a similar process for unmounting.

Unmount and cleanup:

stop debuggerd
mount -o rw,remount /system /system
echo "#!/system/bin/sh" > /system/bin/debuggerd
echo "toolbox umount /data/media/0/usbStorage/sda1" >> /system/bin/debuggerd
echo "toolbox rmdir /data/media/0/usbStorage/sda1" >> /system/bin/debuggerd
echo "toolbox rmdir /data/media/0/usbStorage" >> /system/bin/debuggerd
echo "echo 1 > /data/data/eu.chainfire.stickmount/ready" >> /system/bin/debuggerd
chown root.shell /system/bin/debuggerd
chmod 755 /system/bin/debuggerd
mount -o ro,remount /system /system
start debuggerd
exit

Return to initial state:

stop debuggerd
mount -o rw,remount /system /system
cat /system/bin/debuggerd.backup > /system/bin/debuggerd
chown root.shell /system/bin/debuggerd
chmod 755 /system/bin/debuggerd
mount -o ro,remount /system /system
start debuggerd
exit
