The thing to realise in your script is that only 1 string is passed to the
a() function. The other 2 `$*' are elided since they're not in quotes and
empty. And, `"$*"' ends up (ie. as $1) to a() as `original 3 args ($1, $2, $3) are empty with only the 2 separators in between
'em.

Yes, except this doesn't work (as expected) with bsdmalloc because it

The random file is generated anew each time an distrib. image is built.
If one needs 256 bits to seed /dev/random, then a 32K random file should
