I add new feature that Load multiple camera configuration files.

If you use multiple camera, store multiple configration files in "/boot/octpi.txt/*.txt".
configration file format is same as original "/boot/octpi.txt".

Looks cool, have you tested this?

Ok noted this will break current usage because you are turning octopi.txt in to a folder.
Usually if you want to have a configuration folder you should call it octopi.conf.d/
I can't find where its written in a spec, but this explains it:

Looks cool, have you tested this?

I should say no, because I don't set-up a image building environment now.
I tested just my modified script, by overwrite '/root/bin/webcamd' on Raspberry Pi with OctoPi 0.16.0.

Ok noted this will break current usage because you are turning octopi.txt in to a folder.

My modified script checks that a type of '/boot/octopi.txt' is a file or not.
Then, load '/boot/octopi.txt' if file, otherwise try to load '/boot/octopi.txt/*.txt' .

Usually if you want to have a configuration folder you should call it octopi.conf.d/

Yes I know. My thought is compatibility on migration.
But, you indicated priority that a directory naming policy is higher than a compatibility. I will modify my script.

Ok, once you change it to octopi.conf.d/ I'll merge it so we can test it.

I changed to "/boot/octopi.conf.d/" and built boot image on Ubuntu x64.
It can boot my Raspberry Pi 3B+. But it has something strange.
Even though I have not connected a video device, it is existed that /dev/video0,10, 11, 12. it is diffarent between octopi v0.16.0 .

If you are building against the latest base image, they might have changed driver stuff. Its fairly new and we didn't enough tests yet.

'/dev/video10,11,12 and video0' issue is caused by raspbian (current 'https://downloads.raspberrypi.org/raspbian_lite_latest' is '2019-06-20-raspbian-buster-lite.zip')

I download previous raspbian ( 'https://downloads.raspberrypi.org/raspbian_lite/images/raspbian_lite-2019-04-09/2019-04-08-raspbian-stretch-lite.zip' ) and build octopi boot image.
It looks same as octopi v0.16.0 with on my Raspberry Pi 3B+ . (nothing here is '/dev/video*', if not connected a video device, or only connect pi-camera.)

camera="auto" for raspi-cam is not working. I will fix it.
And I plan to change webcamd startup mechanism from init.d to systemd.

Ok, just ping me when you are ready for me to pull it

I was done fix issue of "auto" and change to sytemd.
New boot image works fine.

Yes please.

Ok merged cc @foosel Note this moves octopi.txt in to conf.d/octopi.txt.
I am not sure I am happy with that, but I guess we could also just move it back.

Note this moves octopi.txt in to conf.d/octopi.txt.

You are aware that that will wreak havoc with our userbase? I'm sure that I'm not happy with that.

@foosel Ok, managed to have a look and fix it.

@usk-johnny-s if you want to have a look and confirm this works for you it would help.
