- Lemmy code of conduct: https://join-lemmy.org/docs/code_of_conduct.html
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
sudoin Windows. - No porn, no politics, no trolling or ragebaiting.
- Don't come looking for advice, this is not the right community.
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. ๐ฌ๐ง Language/ัะทัะบ/Sprache
- This is primarily an English-speaking community. ๐ฌ๐ง๐ฆ๐บ๐บ๐ธ
- 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. ย
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.

Debian admin here. Even Debian gets regular kernel upgrades that like a reboot afterwards. Security updates are more important than uptime. Also regular testing for clean recovery after a reboot is a must so a power outrage doesn't bring any new surprises with it. Also test your backup restores regularly.
Novice homelaber here, is this just a case of apt update & upgrade or is there different commands for security and kernel updates? Also whatโs your preferred backup/restore software? Thanks!
Kernel updates are usually held back and need to be selected manually. E.g. apt-get install linux-image-amd64.
I prefer rsync for private backups and employ bareos in my company for all servers.
