Yes I did change that as well (as /var isn't part of the root partition).
I see. How did you change it? Because in 9.99 some things have changed:
rndseed=/var/db/entropy-file
on a line of its own no longer works. You have to attach it to a
menu= line:
menu=Boot normally:rndseed /var/db/entropy-file;boot
The same with some other directives like `gop='.
/etc/rc.d/random_seed will do this (again) later anyway.
Yes.
I know how to seed it -- but that's not the problem -- the hardware
should be providing plenty of entropy.
As riastradh@ mentioned, in 9.99 only true HWRNGs like RDSEED/RDRAND will
be used. Other, estimated, sources are no longer "counted". mrg@ says
your CPU doesn't have the necessary instructions, so that means no RNs
for you (on 9.99) ;).
cpuctl identify 0 should tell you if your CPU has RDSEED/RDRAND.
