How would I set these options in LEDE that udev would take care of in traditional desktop linux:
# Create PPS device and set low_latency. Add udev rules.
# Create /etc/udev/rules.d/gps.rules.
KERNEL=="ttyS2", RUN+="/bin/setserial -v /dev/%k low_latency"
KERNEL=="ttyS2", RUN+="/usr/sbin/ldattach pps /dev/%k"
Where can I get older x86 binaries for
These don't seem to be available via opkg anymore.
I think the closest LEDE replacement would be a short shell script in
Do I have to do anything else to run the file at boot? It isn't being executed.

Thanks to jow on IRC, the solution is not $ACTION=ifup, it is "add". There is no ifup action for tty events.
