alternative operating-systems

[2021/04,2023/10]

Alternatives away from RPIOS which has become bloated and infected with Systemd Virus.

FreeBSD

FreeBSD 13 has some device-drivers, but lacks wireless. FreeBSD has elevated RPI to 'Tier 1' status (meaning complete support).

NetBSD

NetBSD 10 has almost all RPI device-drivers.

Alpine Linux

Alpine Linux is a very minimal Linux system (what RPIs need).

Void Linux

Void Linux offers installers specific to various RPI models.

Haiku (BeOS clone)

Haiku is worth watching, its developers have begun porting to RPI. (More about BeOS/Haiku.)

Speed of compiling GNU Emacs

[2021/05]

Not equal comparisons. Variously compiled Emacs versions 24..27 (Mac Mini G4 limited to Emacs-24). Emacs usually was compiled in temp RAM on systems having sufficient ample memory.
