I go for the unoriginal but oh so simple: location-type-No

So HL-SRV-01 is “homelab server no 1”

HS-DSK-02 is “House desktop no2”

NA-LPT-01 is “Not Applicable” because this is my admin laptop that I expect to move around a lot so I always treat it as high-risk.

I consider open source software to be community owned/maintained so I never liked the idea of selling the software. It makes much more sense to my eyes to sell services surrounding the software be it support, customizations, or even hosted services.

I can’t really get over selling a “license” for a software that is expected to still be maintained by unpaid contributors. Especially under an AGPL license where any licensing changes has to be approved by every contributors.
