Where document service which is disabled after F16->F17 upgrade via yum

[Adam Tkac]

Hello all,

named service is disabled after F16->F17 update via yum due to
initscripts->systemd conversion. It wasn't possible to keep it enabled when was
due to too many differences between initscripts and systemd unit files.

As written in https://bugzilla.redhat.com/show_bug.cgi?id=808889, this
backward incompatibility should be documented somewhere but I'm not sure where.
Can you please point me where should I document it? Thank you in advance.

Regards, Adam
