Awk's rand seems to be seeded by the current epoch seconds, but in this

Looks good to me. I'd even go as far as implementing your nanosecond
approach as the seed for AWK's 'srand()'. Maybe set up a tiny function to
use whenever we want a random integer:
random_int () {
awk \
-v nanosecond_seed=$(date +%N) \
'BEGIN {
srand( nanosecond_seed )
print int ( rand() * 255 + 1 )
}'
}
Then we can just call 'random_int' in place of $RANDOM...
