In order to work with openwrt the scripts listed in man random should be modified to save the random-seed file in the etc folder (/var and /tmp folder are tmpfs)

This might be implemented easy. The problem is that most of the times the SOHO routers suffer a hardware reset which would make the shutdown script useless. I think a cron entry should do the trick. What do you guys think ?

I give second witness that this should be addressed in order to rectify a potential weakness. The cron entry sounds like a good way to do this.
