Unplugging all LMI-related functionalities in cubecos is fine. However, hex is a designed to be standalone and reusable for future appliance-like products. That's also why it is a separate repo. I'd say we keep hex as is while all these changes take place in cubecos.

[Eandalf-Bigstack]

Keeping LMI in cpp related files would be fine since, for CubeCOS, these code in Hex would not take effect. However, scripts/makehotfix, scripts/makehotfixdraft, and scripts/mountrootfs these three files would affect the file system, particularly, folder /var/www/html and /var/www/lmi. Are we going to keep /var/www/lmi in those scripts and maintain the permission of /var/www/html in CubeCOS?

[leechienpang]

I don't see any harm keeping the behaviors of makehotfixdraft, make hotfix and mountrootfs. The only leftover that users can notice is probably seeing some "LMI" strings when they use hex specific CLI but no big deal.

[Eandalf-Bigstack]

Got it, would revert the changes.
