this strncpy is different from the one above regarding the number of characters to be copied. While both are technically correct they should at least be unified.

Can you suggest a clean solution? (You are the C dev... ;-) ).

str(n)cpy is always tricky. I would do the getenv only once. Then strdup either the result or the default. And free the dupped string at shutdown.

@uli42 Can you help with this MR and fine-polish it? Your C is so much better than mine.

I am currently limited hw-wise. But I think this looks good except that you
use strncpy in two different ways. You should make them identical regarding
the length argument.
I suggest you test and merge it. You can leave this ticket open and I will
revisit eventually.
