We've long held that the install tag is bad and should be split into system-installation and software-installation.
There are over 200 instances that need to be disambiguated manually, so we're doing this mostly organically and it takes forever. Granted, it could go quicker if we set our collective minds to it, but we don't want to fill the front page with that so we'd keep doing a handful at a time.
Unfortunately, the questions keep coming in. I try to catch them early but some always fall through the cracks.
Please blacklist install so that we can clean up the remaining occurrences. The tag wiki and excerpt for install clearly states what tags to use instead.
