[PATCH 1/2] [package] babeld: update to 0.98, fix scripts
Gabriel Kerneis
kerneis at pps.jussieu.fr
Mon Feb 15 18:21:39 UTC 2010
- Full-featured UCI configuration file (no need for babeld.conf).
- Do not check the pid file (useless) and ahcpd script (harmful).
- Make /etc/config/babeld a config file.
- Launch at most one instance of babeld.
- Add status and reload options to init script.
- 8 February 2010: babeld 0.98:
* Implement the ability to prefer Babel routes to external routes
according to the kernel priority (-A).
* Implement the ability to redistribute "boot" routes when the
protocol is explicitly specified on the "redistribute" line.
* Allow trailing whitespace in config file.
