Re: [Cerowrt-devel] how is everyone's uptime?

[Dave Taht <dave.taht@gmail.com>]

well, you would have crashed mysteriously in another 3-4 weeks anyway,
given the growth there. :/

One of the things that bothers me about all the folks trying to use
debian for embedded use is that they don't fix syslogging in general,
and thus a crash is merely a matter of time and flash space.

In embedded, we care a lot about slow memory leaks, and things like
logfiles growing out of control, and openwrt takes care of most of
that for you. But not all of it. You want zero memory growth,
transparent restarts of all daemons from crashes, etc....

I am also increasingly impressed by what the low memory footprint of
openwrt does for you. Even on the rangeley (with 2MB cache) it seems
tons faster and more resistant to temporary glitches to have such a
small working set.

I am thinking a lot of the work that opendaylight, etc, is wasted,
they should just be running a smaller OS....
