Just realized my code is slightly wrong for you since you wanted hex
values rather than alphanumeric string.
The first line should be:
<% range = [*'0'..'9',*'a'..'f'] -%>

The "<% range ... -%>" can be anywhere in your template as long as
it's before where you generate the random value. I usually put stuff
like that near the top of the template. If you're generating multiple
random values you only need to specify it once.

I have tried using a self written shell script which generates the

in the template. That unfortunately didn't work.
I suspect I have to write a small embedded ruby template / code
snipplet to generate this structure but after some web search I still
have no idea how to do that in Embedded Ruby. Does somebody have a
short erb suggestion?
