That code actually isn't called.  It's used by "isarray" to tell me whether
or not a var is an array.

The code that doesn't work is the line with the comment "line 233".
(which is now line 235 from the latest error message.

Note that according to the "printf in "read_actuals", the values are 
correctly
being read in from my "here var".

Note, you can't use an assignment there.

It's reading names+hwaddrs of the net devs @ boot
in "get_net_IFnames_hwaddrs".  That requires line and field
splitting.


Now that I'm writing about it -- I'm thinking that
it doesn't like me using the hwaddr's  @ boot time as hash subscripts.

That's what I don't understand.  It works "normally", but
why would "hashes" fail at boot?  I couldn't think of how they'd
be implemented to use some non-existent service, so I don't
know which resource lack is causing the fail.

Yeah, like multiple lines and fields in "$var"...
