Job interview tomorrow for entry level IT position... please help me understand what this position entails so I am prepared

The job title is simply 'Support Technician'

Basically what I'm confused about is two of the main job requirements are 'Linux application support' and 'application log experience'

Apparently these aren't easily Google-able things... I have experience with Linux but its mostly fundamentals... please, can anyone help me understand what this job may entail? Here is the description as well:

"Client employer is seeking a Support Technician to help implement new retail stores. Duties include following a set of instructions (application steps) to implement the new stores. They will be provided with pre-defined orders and instructions and are expected to document, as well as make repeatable, new releases that come out."

It all seems pretty vague to me but I'm thinking the answer lies in those two industry-jargon phrases 'Linux application support' and 'application log experience'

Huge thanks in advance for any help!
