[debian-mysql] Bug#864943: mariadb-server-10.1: Starting mariadb service does not terminate

[Ondřej Surý]

Control: tags -1 +moreinfo

Hi Thomas,

I am afraid that we will need to have a reproducer outside of the Docker
or find what's causing the Docker instance to be stuck[*]. There are too
much unknown variables when using Docker, and it's quite hard to debug.

* - or at least provide a full log of what is happening inside your
Docker container.

Cheers,
