Nexoniarz is the sole author and SchOS was never published under
Apache-2.0, so this is a straight relicence. LICENSE is the FSF GPLv2 text,
every first-party SPDX header moves to GPL-2.0-or-later, and NOTICE,
README.md, docs/licensing.md and the site say so. projects/schfs-linux
follows the rest of the tree.
The GPL gives copyleft: a fork has to ship its source. It also lifts the
old "Linux drivers, never" rule, since GPL-2.0-only code combines with
GPL-2.0-or-later. "Or later" leaves room for GPLv3, but one binary still
has to pick one version, so docs/licensing.md now keeps Apache-2.0 and
GPLv3 code out of the kernel to keep Linux code possible there. BSD
4-clause code goes from "avoid" to "no", because the advertising clause
is GPL-incompatible.
LDLS still ships no .ko. That boundary is now project policy rather than
a legal requirement, and ldls.md, devices.md and licensing.md section 6
say so. refmod declares license=GPL, and ldls-check passes (27 checks).

tools/windows/ .ps1 (pwsh, so usable from Linux and macOS too)
tools/posix/ .sh
tools/python/ .py
tools/ .c and .pl
The .c and .pl files stay at the top level because they are not
host-specific: the build compiles or invokes them on every platform.
Call sites updated in the Makefile, ports/mk/port.mk, docs and the
project memory. The one thing that does not survive a move on its own is
a script deriving the repo root from its own location -- all nine
PowerShell tools used Split-Path $PSScriptRoot -Parent, and memory-sync.sh
used dirname/.., both of which quietly become tools/ one level deeper.
Two levels now.
Two pre-existing Windows failures surfaced while verifying, both real and
neither caused by the move:
- schfs_fsck.c did not compile under mingw at all: --extract uses
POSIX mkdir(path,mode), symlink() and link(), none of which mingw
has. That took the whole tool with it, and `make schfs-check` with
it. mkdir maps to _mkdir; symlink and link fail loudly rather than
writing a regular file in their place, because an extracted tree
that differs from the image while reporting success defeats the
point of --extract.
- the round-trip test then failed at `ln -s`, since Git Bash cannot
create symlinks without developer mode. It skips with a message now.
Not a fudge: mkschfs's mingw build cannot see a symlink either, so
the test would have compared a tree with none against an image with
none and called it a pass -- coverage reporting itself as present
while being absent.
Verified on Windows: build clean, all seven bootcheck suites green,
make schfs-check passes.
