might have devices that do have sufficient entropy. So before we make
this a SlugOS-specific build-time thing, is there no way we can change
this at run time? (config file, environment variable, something like that?)

Hi Mike, AFAIK, systems with sufficient entropy will provide the same or similar level of randomness on /dev/urandom and /dev/random as long as there is enoughMessage 1 of 4 , Jul 2, 2008View SourceHi Mike,
AFAIK, systems with sufficient entropy will provide the same or similar level of randomness on /dev/urandom and /dev/random as long as there is enough "noise" in the system. With urandom you just cannot guarantee that you get the highest possible randomness. At least that's what "man 4 random" suggests.
I do not know of any runtime settings which could adjust apr's behavior. But looking at the apache bug report https://issues.apache.org/bugzilla/show_bug.cgi?id=44881 apr 1.3.x seems to have switched to preferring /dev/urandom already, so alternatively the apr recipe could patch configure.in according to
Unfortunately the subversion bug report does not comment on that change in apr yet...
