I missed the twitter poll but from my perspective as someone involved in
making and releasing such updates for SUSE customers Monday disclosures
tend to work for us but only due to timezones, generally disclosure
times happen into the late afternoon evening, which means that if
lengthy QA tests were left running over the weekend our QA team will
have time to review the results during Monday and we will be ready to
release. I am guessing that some other distro's wouldn't end up with
this luxury. Having said that it will often depend on the amount of
total time we have and the size of the test suite, having said that many
of our automated tests will finish over night.
I guess for distro's who employ people to fix security issues, a Monday
morning / lunch time disclosure is mostly going to mean that everyone
will aim to have update's ready on the Friday night if possible which
doesn't really help with keeping embargo times as short as practical. On
the other hand it might give people patching issues in there spare time
more of a chance.
