Bug#931658: runit-init: Boot hangs with QEMU if openssh-server is installed

[Lorenzo Puliti <lorenzo.ru.g@gmail.com>]

Package: runit-init
Version: 2.1.2-30
Severity: normal

Dear runit and openssh maintainers,

when rebooting a QEMU image (debian Sid, from autopkgtest) with runit-init, if ssh server 
is installed and enabled, the system hangs at boot because the ssh server is stuck and unresponsive 
(see bug 930758 message 50).
Also, I suspect that the same problem can happen with Virtualbox (see 838480 message 49).
I'm not sure if this is a bug with runit or openssh-server and it's not easy for me to
understand what triggers this bug; for example in my system i have ssh server
and runit as init and all is working as expected..

Lorenzo
