Pau Espin Pedrol gerrit-no-reply at lists.osmocom.orgHello Neels Hofmeyr, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/3711 to look at the new patch set (#2). OsmoGsmTester: Move coredump section and add reference to kernel.core_pattern sysctl This section is moved further below in order to have it after section which explains how to create user jenkins and osmo-gsm-tester group, as we need this group already created anyway for the config to work correctly.
