Hello,

This startup / shutdown scheme apply to nominal cases where you don't need to reboot your system :)

Building a brand new box may require you to restart dahdi a bunch of times : "no span" error [1], digium firmware not downloading [2], forgetting Europe requires E1 line mode, new telco uncertain if using crc4 …
More, in case your telco is failing, he'll often ask you to reset on your side first. Restarting dahdi feels way more convenient than rebooting a distant system.

Red a bunch of READMEs of the packages installed before posting, not sure i red this one. Maybe a "Manual startup / shutdown" section would be welcome ;)

This file is missing on my side (1:2.10.0.1-1), but asterisk seems to be aware of the channels. Not sure how.

Thank you for your answer,
