Package: openssh-server
Version: 1:7.9p1-1
Severity: normal

Dear Maintainer,

After yesterdays upgrade to 7.9p1 in testing, openssh-server delays my system's
boot by quite some time.
In fact, it is always the first and slowest to start process in systemd-analyze
blame, with times varying from < 20 seconds most of the time

         19.044s ssh.service
          2.083s ifupdown-wait-online.service

to this insane 100+ second delay I found out yesterday

    1min 24.779s ssh.service
          1.120s ifupdown-wait-online.service

Even those 20 seconds are a lot, because due to its delay, my boot time (as
mentioned by systemd-analyze) increased from 5-7 seconds to 20+. The os is on
an ssd drive obviously.

If it helps, I have ipv6 disabled system-wide with this kernel parameter:
ipv6.disable=1.
