fastfetch builds and runs on SchOS:
OS: SchOS 0.1.0 x86_64
Kernel: SchIFT 0.1.0
Shell: sh Terminal: schinit
CPU: AMD Ryzen 7 5700G
Memory: 11.94 MiB / 1016.93 MiB (1%)
Disk (/): 4.64 MiB / 31.25 MiB (15%) - schfs
Here because it is a good acceptance test, not because SchOS needs a fetch
tool. It is ~410 C files somebody else wrote against Linux rather than against
our bugs, and running it exercises procfs, per-process directories, uname,
statfs, getpwuid, terminal detection by walking ppid, and an ANSI renderer all
at once -- which is the shape docs/plan/roadmap.md asked for when the previous
full-stack test was removed.
patches/ is empty and should stay that way. When fastfetch cannot detect
something the answer is to give the system the thing it is looking for, because
every other program looks for the same things. Its first run reported four
misses and they are being worked in that order:
OS: Could not detect OS -> /etc/os-release, this commit
Local IP: getifaddrs() failed -> AF_NETLINK, next
Host: not set by O.E.M. -> DMI in /sys, later
Users: Unable to detect any users -> utmp, a userland convention
Four things the port needs that say nothing about SchOS, recorded in the
Makefile because each cost time to find:
* Every ENABLE_* off. All 29 files calling dlopen are optional detection
modules, and ENABLE_THREADS=OFF removes the single pthread_create -- which
matters, because clone() here does not share an address space.
* -isystem the compiler's own include dir. -nostdinc removes it too, and
cpuid.h is emitted by the compiler with no musl equivalent.
* Linux UAPI headers. musl ships none by design; a musl toolchain is normally
paired with a separate linux-headers install.
* libgcc on the link line, and libc twice -- libgcc pulls symbols back out of
it (__popcountdi2), and a static link resolves left to right.
The toolchain settings are a CMake toolchain file rather than command-line
flags because CMAKE_*_INIT variables are only honoured when the cache is first
created. Reconfiguring an existing build directory ignores them silently.
Also rebuilt musl: build/ports/musl/prefix/bin/musl-gcc had the pre-move path
/home/nexoniarz/Documents/SchOS baked in by configure. The tree does not use
that wrapper -- it links with explicit -I/-L and crt objects -- so nothing was
broken by it, but it was stale and would mislead anyone who found it.

Fetched by ports/lwip and compiled into the kernel -- it is the TCP/IP stack,
|
|
not a userland library, so it is present in every built kernel image rather
|
|
than in a binary under /bin. The port layer written for SchOS
|
|
(kernel/net/lwip/) is Apache-2.0 and is not part of lwIP; lwIP's own sources
|
|
are unmodified. Clause 3 is a no-endorsement term, not the four-clause
|
|
advertising requirement, so it combines with Apache-2.0 without difficulty.

usb.ids -- USB vendor and product database BSD 3-Clause (dual-licensed)
|

--------------------------------------------------------------------------------
|
|
Maintained by Stephen J. Gowdy <linux.usb.ids@gmail.com>
|
|
http://www.linux-usb.org/usb.ids
|
|
|
|
Distributed by its maintainer under the terms of *either* the GNU General
|
|
Public License version 2 or later, *or* the 3-clause BSD Licence. SchOS takes
|
|
the BSD option; the GPL option is not exercised and could not be, since
|
|
Apache-2.0 and GPL-2.0-only cannot be combined (see docs/licensing.md section
|
|
2).
|
|
|
|
Shipped verbatim as /usr/share/usb.ids. Cached in dist/ and refreshed with
|
|
`make usb-ids`, never automatically -- the version and date are in the file's
|
|
own header, so what shipped is always knowable.

Copyright 2020 The JetBrains Mono Project Authors

|
|
|

Shipped as /usr/share/fonts/JetBrainsMono-Regular.ttf, from ports/JetBrains_Mono
|

(full licence text at ports/JetBrains_Mono/OFL.txt). Intended for the terminal

Under the SIL Open Font License 1.1 the font remains under OFL even inside this

Apache-2.0 system -- that does not reach any other part of SchOS -- and it may
|
|
not be sold on its own. Bundling it with an operating system is expressly
|
|
permitted. JetBrains Mono declares no Reserved Font Name, so a modified version
|
|
(a pre-rasterised bitmap, for instance) may keep the name.

kernel/fs/fs.c and parts of tools/mkfs.c derive from this project, which extends

xv6's file system with features SchOS still uses today:

bucket layout), after Daniel Phillips, "A Directory Index for EXT2",

Licensed under the MIT License, which permits this use and requires that the
|
|
copyright notice and permission notice be retained. This entry is that
|
|
retention; it was missing until 2026-08-09 and is recorded here regardless of
|
|
what happens to the code, because the obligation attaches to every copy already

Distinct from xv6 itself (LICENSE.MIT), which this project in turn derives from.

================================================================================

The build downloads upstream tarballs into dist/ and applies the patches in
|
|
ports/<name>/patches/. Nothing in ports/ is SchOS code; do not add first-party
|
|
work there. See docs/layout.md.
|
|
|
|
Licence questions -- what may be copied in, what may never be, and how to check
|
|
a NetBSD file's clause before using it -- are worked through in

docs/licensing.md.
