RE: Installation of SnakeOil OS 1.3.0 on RPi 4 with Raspberry Pi OS - miksi - 21-Dec-2024

Everything remains on home folder after reboot. I’m using this folder for various compilations like for building MPD (with SACD Iso support, mympd… etc). I also have ssh client with root privileges.

What do you mean home folder? As in your home directory?

There are certain files (databases, binaries, libraries etc) that have to sit outside your home folder (~), in places like /var or /usr for example. Can you SSH into your machine, and run this command:

Code:
sudo mount

I don't think there's any sensitive private information in this command, you can post the output here or as a DM so I can better understand how your setup is.

Home folder is only for my stuff like git cloning, compiling or some temporary stuff. The rest is on var and usr foders like you intended to be. I didn't change content of anything in these folders after installation of SnakeOil OS but something removes the scanned database when reboot command is issued on mympd system web page or trough sudo reboot.
Also when I mount NFS share it gets removed from mounted list after reboot so I added my NFS share on fstab.

Here's content of var/www/players and usr/local/bin folders:

Within new mpd-SACD folder I've copied files from mpd-v23 folder and adjusted content of some of the scripts to reflect change of folder name.
But regardless of version of mpd used I can't retain scanned database.

Everything looks good. Looks like mympd process (probably under the user mympd) do not have write permission to write out the database. That's why on reboot everything's gone. Past 2 years really made me degrade the quality of this Snakeoil software, and there's so much catch up to do. Sad

Can you double check if this path exists? /var/lib/mympd

And if it doesn't, run this:
Code:
mkdir -p /var/local/mympd
[code]

And make sure the file permissions are correct, it should be mympd:mympd. You can change it via this command
[code]
sudo chown mympd:mympd /var/lib/mympd -R

I'm pretty sure it already is, just unsure how/why it's not working (just yet)....

RE: Installation of SnakeOil OS 1.3.0 on RPi 4 with Raspberry Pi OS - miksi - 23-Dec-2024

/var/lib/mympd exists. I tried again, mpd-v23 works as expected but my compiled mpd-SACD after start always does full rescan of music libraries. So I need to check compilation configuration of this mpd
