I am getting a compile error here and below for the free of uuid.
error: assignment discards 'const' qualifier from pointer target type
error: passing argument 1 of 'free' discards 'const' qualifier from
pointer target type [-Werror]

Removing the const in the declaration works... for me.

Strange - mine didn't complain, but one would also think that the prior
code doing a uuid = strdup(dominfo->uuid); would elicit the same issue!

Anyway, adjusted the definition from "const char *uuid" to just "char

In actually reading and thinking about the code, do you think a
"free(dominfo->uuid);" prior to the setting should be added too? In the
event it was the empty string?  Not sure how it gets set that way, but
since cleanup_dominfo() would free() it if it was "" or whatever real
value is, then I suppose better safe than sorry.
Yeah, to be 100% sure I guess just freeing it is ok... :-)
