Let's discuss alternatives to GNU/Linux! So, post here, if you need recommendations or help. Personally, I believe that *BSD (minus FreeBSD) are the most realistic alternatives for Linux.

==OpenBSD==
https://www.openbsd.org/
+ The default installation is very secure. OpenBSD has many interesting security features.
+ Competent developers who are committed to developing their OS
+/- Its developers expect you to fix problems yourself

==NetBSD==
https://netbsd.org/
+ Supports a ''huge'' number of CPU architectures: "Of course it runs NetBSD"
+ pkgsrc*
+ Very lightweight: it has '''even''' lower system requirements than FreeBSD, OpenBSD or Dragonfly BSD
(Remember to use the installer's configuration menu to install package manager)

==Dragonfly BSD==
https://www.dragonflybsd.org/
+ Has the best multi-core performance
+ Has the best file system (HAMMER and HAMMER2)
? I think Dragonfly BSD has smaller community than OpenBSD or NetBSD



*Many other operating systems support pkgsrc since it's very portable, see https://www.pkgsrc.org/
Also, if you want to install pkgsrc on OpenBSD, please consider backing up (E.G. with cp) the original package mangager's binaries.


==General tips and resources==
* pkgsrc guide: https://www.pkgsrc.org/
* The OpenBSD FAQ (the installation guide): https://www.openbsd.org/faq/index.html
* OpenBSD gaming resource: https://mrsatterly.com/openbsd_games.html
* Rundown of OpenBSD's security features: https://en.wikipedia.org/wiki/OpenBSD_security_features and https://www.openbsd.org/security.html
* Pls rember that wen you feel scare or frigten, never fforget to reed manual. (esp. '''man afterboot''')
* BSD utilities can behave slightly differently (have different command-line switches) than the essential utilities provided by GNU. Read The Fine Manual. BSD tar is a good example of this.
* You probably want to use the korn shell (ksh)
* Remember to check ''info''-pages in addition to man-pages. The info-pages of GNU programs are usually more comprehensive than their man-pages.
* When partitioning the disk, the "slices" are basically "partitions" inside regular partitions.


==Avoid these==
- FreeBSD (it sucks a CoC)
- TrueOS  (it's unstable)
- GNU/Linux (it sucks a CoC; it wont get ruined over night, however, the code quality is expected to lower over the course of next 2-5 years. The SJW community is extremely toxic)
- MINIX (very outdated programs; it isn't suitable for desktop use)
- OpenIndiana (An anon said it has very outdated programs)
- Microsoft Windows (it's botnet)
- ReactOS (it's not ready yet)
- PureDarwin (not very usable)
- 9front (Sucks a CoC. See https://track8.mixtape.moe/dbvmmr.txt)
