Module Name: src
Committed By: brad
Date: Sat Apr 30 13:48:09 UTC 2022
Modified Files:
src/etc/rc.d: gpio
src/share/man/man5: gpio.conf.5
Log Message:
Like /etc/rc.d/network, add the ability to put a '!' character as the
first character in /etc/gpio.conf and have the rest evaluated in a
shell. It is useful to be able to do actions after setting up gpio
pins or attaching gpioiic(4).
