I ignore that part because it doesn’t pose a problem for the user. If you’re on a distro X, you know what command to type to install a package using its package manager. For the same reason, OP didn’t care to explain how to power on your computer. Or do you expect a meme to be a comprehensive guide on how to install sshfs on all major distros? Really? Maybe the real problem is that some people don’t understand what a meme is.
