Hardware Requirements

TODO

This article is a work in progress.

Apostrophy OS is built on a system with the following specifications:

Hardware	Make/Model/Qty
CPU	AMD Threadripper Pro
Memory	512 GB DDR4 3200Mhz RAM 1
Disk	4x 4TB Kingston NVMe
	10x Western Digital 4TB Red Caviar
OS	Fedora (current or current minus one)
Airco	ecofort CoolAir 9+ (because AMD 2)
UPS	APC Pro 1600 S 3

The signing system is a different system, about which you could dream, or speculate, or care less.

Tips

Mind Your Build Hierarchy Path Length

While you may of course originally develop in a hierarchy located at /home/your-username/devel/src/aphy/aphyos/build-topic1/, it should be noted this path can become too long for certain build commands (and effectively run out of MAX_ARGS_LEN).

If you encounter errors such as the following

$ make vts
(...)
posix_spawn: Argument list too long
09:42:16 ninja failed with: exit status 1

#### failed to build some targets (03:00 (mm:ss)) ####

then perhaps temporarily (or permanently) bind-mount to an effectively much shorter path length as examplified below, keeping in mind to perform at least one clean build.

$ sudo mkdir /srv/aphy
$ sudo mount -o bind \
    /home/your-username/devel/src/aphy/aphyos/build-topic1/ \
    /srv/aphy
$ cd /srv/aphy

Footnotes

1. It shouldn't really take that much, but the release engineer's favorite editor is emacs, OK? ↩

2. It's not just a meme. ↩

3. Not even XFS on NVMe is fast enough to risk corrupting up to 16TB worth of small files. ↩
