-----------------------------------------
I'm happy to merge this oneliner if we have another pair of eyes confirming
that it doesn't hurt.
> Check the current user in SysV init script
> ------------------------------------------
>
> Key: SOLR-14585
> URL: https://issues.apache.org/jira/browse/SOLR-14585
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: scripts and tools
> Affects Versions: 8.5.2
> Reporter: Roman Kosenko
> Priority: Minor
> Labels: sysinit, systemd
> Attachments: init.d-solr.diff
>
>
> While SOLR-14410 is still open I propose a quick fix/improvement for init.d
> script - check the current user and, if it is the same as RUNAS user, then
> don't execute "su".
>
> Background:
> Systemd has backward compatibility with SysV and able to run scripts from
> /etc/init.d, but SELinux policies in many distros encourage changing user
> before this stage and prohibits executing of "su" binary, so it would be
> logical to do this at systemd level
> (/etc/systemd/system/solr.service.d/override.conf). In this case, the current
> init.d script for Solr is missing one very trivial check - `"$RUNAS" !=
> "$USER"`. See the diff-file in the attachment.
