[pve-devel] [PATCH] Storage::resolv_server gethostbyname replacement explanation

I supplemented the patch with a description regarding the reason for replacing
gethostbyname. It's simply that perl's gethostbyname doesn't support ipv6 the
way POSIX' gethostbyname(3) does.

An easy way to test this:

$ perl -MData::Dumper -e 'print Dumper(gethostbyname("::1")), "\n";'

While this works with ipv4 addresses. At the same time when asking for an
actual _name_ instead of an ipv6 address, the result shows an address type of
AF_INET, instead of AF_INET6, even if the name is supposed to resolve to ONLY
an ipv6 address.
