Re: [Astlinux-users] My Custom TTS Ulaw Sound Files Delete on Reboot of Thin Client Running Astlinux

Hi Cody,

Great to hear you got it working.

> I don't understand persistent directories yet. 

As typical with embedded appliances, AstLinux's /var/ mount type is "tmpfs" (RAM based, non-persistent).  The flash storage (persistent) is mounted type ext2.

AstLinux uses a "symbolic link" (ln -s ...) in places to create references on the non-persistent /var/ tree that points to persistent storage found in the /mnt/kd/ tree as well as to the read-only AstLinux ext2 flash image.

These "symlinks" can be confusing to follow at first, for example following your "custom-sounds" case ...
--
pbx ~ # ls -l /var/lib/asterisk/sounds/custom-sounds
lrwxrwxrwx    1 root     root            38 Aug 27 16:40 /var/lib/asterisk/sounds/custom-sounds -> /var/tmp/asterisk/sounds/custom-sounds

pbx ~ # ls -l /var/tmp/asterisk/sounds/custom-sounds
lrwxrwxrwx    1 root     root            21 Aug 27 16:41 /var/tmp/asterisk/sounds/custom-sounds -> /mnt/kd/custom-sounds
--
Note the " -> " indicates a symlink reference.

Remember you should only be adding/editing files in the /mnt/kd/ tree path, though if you know a symlink points to the /mnt/kd/ tree path you can use the symlink name as a convenience if you wish.

The /mnt/kd/custom-sounds did not exist before I did the mkdir. I checked. I made the directory, then I used the CLI to mount a flash drive and put the ulaw files back in /var/lib/asterisk/sounds/custom-sounds. They remained this time after a reboot. I don't understand persistent directories yet. When I use winSCP to look at the tree structure, I see the same directories repeated under /stat and /tmp for /var/lib/asterisk/sounds/custom-sounds and other directories. I am not fully understanding Linux directories yet. The book I'm reading is not great at explaining Linux either.

When I reboot the thin client Astlinux is running on, the directory remains but the files are deleted. I used the CLI to make the directory and move the files I made into it. Everything works fine until a reboot, and then those files in that directory are gone. Would someone please advise me as to what I am doing wrong? Keep in mind that I am an Asterisk and Linux novice.
