"etc."? As in, that's NOT EVEN THE ENTIRE LIST ?!? Come on. Get real here. You say in the subject that this is a "server". Therefore /home is not an issue. There aren't any end users filling up their home directories to worry about. Separate /usr is basically no longer a supported configuration. The usrmerge stuff, and so on... well, I won't drone on about it. Separate /tmp is a whole can of worms all by itself. You might just want to make that a RAM-based file system. There are a few varieties of that. Out of the partitions you listed, pretty much the only one that makes sense to separate on certain kinds of servers is /var. And even then, you might be better off separating some *subdirectory* (or multiple subdirectories) of /var instead. It depends on what this "server" is supposed to do. Is it a mail server? Then the mail queue might be something you separate. A database server? Then perhaps the directory where the database files live could be separated. But really, it sounds like you're just blindly following some *massively* outdated and deprecated advice which serves no real purpose in your actual situation. You said that you have the ability to boot the server in rescue mode remotely. If you can do that and *shrink* the root file system, you could reallocate some of the disk space to a separate /var, but that's going to be a pain in the ass to do, and you shouldn't even bother unless there's an actual justification for it.
