Bug#929730: systemd: boot-and-services test expects first kernel log line, but not always in logs

[Dan Streetman]

Package: systemd
Version: 241-5
Severity: normal
Tags: patch
User: ubuntu-de...@lists.ubuntu.com

Dear Maintainer,

boot-and-services test expects the first(ish) kernel log line to be in the 
system logs, but that is not guaranteed to be in the logs.

-- Package-specific info:


  * d/t/boot-and-services:
    - don't fail if some kernel msgs are missed (LP: #1830479)


Thanks for considering the patch.
