Should NetBSD be shipping a default boot.cfg in /usr/share/examples
(*) - thinking primarily of people who have upgraded from earlier
NetBSD versions.
I was looking to add in rndseed & just generally sync with the latest
version but there doesn't seem to be a default example shipped with
the syste

When the system never had enough entropy.
I would consider this a bug in the setup of the system, but as of now we do
not deal with it at all during installation, and on systems that are not
installed (bootabl

When there's too little entropy to begin with. Once you have
gathered enough, it unblocks, and never blocks again.
This is assuming default settings. If you actually want entropy
to run out, you can do "

It would already be conditional in the sense that it's only printed if
the system has no entropy. If a multi-user system is lacking entropy,

All,
The following patch will cause a kernel message to be logged when a
process blocks on /dev/random or some other randomness API. It may
help some users befuddled by pkgsrc builds blocking on /dev/random,
and I'm finding it useful when testing changes aimed at fixing PR
