Moving Homebridge storage path: /var/lib/homebridge ( to use rpi image with fs overlay )
### Raspberry Pi Model

Raspberry Pi 4 B

### Current Situation

hi ,
How to move homebridge storage to different mount point. 

from  "/var/lib/homebridge"  to  "/data/my-data/hb" 

I want to lock the  OS filesystem with FILESSYSTEM-OVERLAY option , 
But keep one r/w mount point on the usb/sdcard for homebridge plugin and accessories.

If homebridge storage is on  OS partition , then my pairing and accessories will be cleared on reboot   

I have made my master disk  with "homebridge-raspbian-image" added  a  partition with 4gb writeable area. 

after overlay files system is enable by raspi-config  /data  path will be will available for persistence storage ( writable ).    

```
$ cat /etc/fstab
proc            /proc           proc    defaults          0       0
PARTUUID=1369d763-01  /boot/firmware  vfat    defaults          0       2
PARTUUID=1369d763-02  /               ext4    defaults,noatime  0       1
PARTUUID=1369d763-03  /data           ext4    defaults,noatime  0       3
```   
My folder struct on /data will be similar

```
