On my Android (Lollipop) handset, the exact command is "/system/xbin/mount".

Dunno if that's universal or not. Does your phone have that file at that exact location? If so, then you can edit the script and replace the 1575 lines of bloat with these two lines:
Code:
#!/system/bin/sh
/system/xbin/mount /dev/mmcblk1p2 /data
