did as directed, and at first it looked like the config mp3_dir saved, but immediately it went to the error – it doesn’t stay up for long but I assume it was the same error500 again. At any rate, nothing showing in the itunes share.
Hmm.. depends on the error, but it might be a typo on the path (verify that that path really exists via telnet), and also it might be the onfig file not writable. Can fix that with:
$ chmod 666 /opt/etc/mt-daapd/mt-daapd.conf
This is really only secure if you are the only person that logs into the slug — i.e. you aren’t using it as a multiuser device, but I’d guess that to be the case.
