Well how about lxc itself transform any dots to hyphens on just those systems?
Rather than require the majority of sane posix platforms to manually transform
a dotted FQDN to some hyphenated version why not just apply this "magically"
within lxc for the systems that can't cope with a dotted hostname?

Times thousand of hosts compared to just a plain "lxc list"?

I've got at least half a dozen clients with hyphens in their domainnames
so mapping - to dot will result in an invalid domain.
