Removes the "-unix" element and with it any trademark exposure to The
Open Group.
The split follows the ecosystem layout: SchOS is the system, and the
kernel has its own name. Kernel-identity strings are the only places
that take SchIFT -- uname(2) sysname, /proc/version, and the two licence
sentences that say "kernel" outright. That is what every Unix does here:
`uname -s` on Linux reports the kernel, not the distribution. Everything
a user reads as the product -- panic screen, boot menu, error prefixes,
docs, LICENSE, NOTICE -- is SchOS.
schunix.img is schos.img, the logo assets and the musl TLS patch are
renamed, and __SCHUNIX__ is __SCHOS__ (the define and the patch that
consumes it moved together).
Two things the rename broke, both found by the bootcheck suite:
- shmtest wrote "SCHUNIX-MMAP-OK" with a hardcoded length of 15 and
compared it back by hand-counted offsets (m[3]=='U', m[14]=='K').
The shorter marker left the write running two bytes past the literal
and the compare reading past the data, failing a file-backed mmap
that was working correctly. Now written and compared through one
constant with sizeof.
- bootcheck asserted a 31-byte file after appending to
"hello-from-schunix"; the shorter string makes it 29.
Both are the same mistake: a string literal whose length is written out
somewhere else. Full suite green -- base, Tty, Ps, Sock, Fb, Usb, Evdev.

# SchDE — the SchOS Desktop Environment
|
||
|
||
The parts you actually look at: a panel, a launcher, settings, a file
|
||
manager, a terminal.
|
||
|
||
SchDE is a set of ordinary Schcom clients plus whatever shared widget code
|
||
they end up needing. Nothing in it is privileged and nothing in it is
|
||
special — if SchDE can do something that a third-party program could not, the
|
||
line has been drawn in the wrong place.
|
||
|
||
## Status
|
||
|
||
Not started. Last of the three, and deliberately so: there is no point
|
||
designing a panel before there is a compositor to put it on.
|
||
|
||
## What it will need that does not exist yet
|
||
|
||
- **Text rendering.** Everything here is text, and the console's fixed 8×16
|
||
CP437 grid is not usable for it. See phase 4 of `docs/roadmap.md` — a real
|
||
glyph cache and rasteriser, and layout as a library in `lib/` so the
|
||
terminal and the file manager are not each solving it.
|
||
- **A widget toolkit**, however small. Even a panel needs buttons, labels and
|
||
hit testing.
|
||
- **A terminal emulator.** Note the direction: the *kernel* console parses
|
||
ANSI today because it draws directly to the framebuffer. A GUI terminal is
|
||
a client that parses ANSI itself and renders it with proportional-capable
|
||
text. The two do not share code.
