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

/data/
└── my-data
    ├── hb
    │   ├── accessories
    │   ├── auth.json
    │   ├── backups
    │   ├── config.json

Interesting idea

A couple of comments

1 - homebridge uses two directories, with the second being in /opt/homebridge so that needs to be taken into account as well

2 - to keep things simple it is possible to just put the overlay in the original location? I quickly read the docs on FILESYSTEM-OVERLAY and the impression it was feasible

3 - how would file system updates be handled?

hi, The os file system will be in locked to state when you enable FS-OVERLAY every power/reboot will be as per the state when you enabled the FS-OVERLAY where as the /data partition will be updated by homebridge activity ( adding new plugin/accessories ). if any critical OS update is needed , I disable the FS-OVERLAY and do the os update , and then re-enable FS-OVERLAY This is only required if the os nodejs modules needs any updates, Homebridge node modules are in its own directory which is not locked. I have a cron task to reboot the device periodically, once every week. Thanks and Regards [image: ] *Mrutyunjay B Patel*

hi,
BOOKWORM 64 bit image did not work with overerlay-fs enabled.

Going back to my last made version with "Raspbian GNU/Linux Buster (10)"

updated all packages to resent version, but kept nodejs version to 18.xx

apt update/upgrade
nodejs to 18.20.1
homebridge to 1.7.0
zerotier to 1.12

My path on /data/ is read-write .

All working ok
