Sister communities:
Community rules (click to expand)
1. Follow the site-wide rules
2. Be civil
Understand the difference between a joke and an insult.
Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
Don't get baited into back-and-forth insults. We are not animals.
Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
Bigotry will not be tolerated.
3. Post Linux-related content
Including Unix and BSD.
Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
No porn, no politics, no trolling or ragebaiting.
4. No recent reposts
Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
5. π¬π§ Language/ΡΠ·ΡΠΊ/Sprache
This is primarily an English-speaking community. π¬π§π¦πΊπΊπΈ
Comments written in other languages are allowed.
The substance of a post should be comprehensible for people who only speak English.
Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
6. (NEW!) Regarding public figures
We all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations.
Keep discussions polite and free of disparagement.
We are never in possession of all of the facts. Defamatory comments will not be tolerated.
Discussions that get too heated will be locked and offending comments removed.
Please report posts and comments that break these rules!
Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't remove France.

That wouldn't be defense in depth. You want to limit anything that's not necessary as it can become a source of attack. There is no reason root should be enabled.
I don't understand. You will still need to do administrative tasks once in a while so it isn't really unnecessary, and if root can't be logged in, that will mean you will have to use sudo instead, which could be an attack vector just as su.
Why do like, houses have doors man. You gotta eliminate all points of egress for security, maaaan. /s
There's no particular reason to disable root, and with a hardened system, it's not even a problem you need to worry about...
