Nexoniarz works from **two machines** and moved the project to the second on
2026-08-09.

| | Windows desktop | Fedora laptop |
|---|---|---|
| path | `D:\DEV\SchOS` | `/home/nexoniarz/Documents/SchOS` |
| memory key | `D--DEV-SchOS` | `-home-nexoniarz-Documents-SchOS` |

Fedora 44, Ryzen 5 7000-series, RTX 4050, 16 GB DDR5. The GPU is irrelevant to
the build — QEMU runs headless for tests.

`tools/posix/setup-fedora.sh` installs the toolchain (`--check` to only report).
`docs/moving-to-linux.md` is the procedure. Memory moves with
[[schos-memory-sync]]: `import` after arriving, `export` and commit after a
session that learned something.

**Three things only the Linux machine can do**, and they are the reason the move
matters:

1. **`make ports`** builds musl, toybox and mksh from source. Windows cannot do
   it at all — the build skips ports and uses whatever is staged in `sysroot/`,
   which is why `sysroot/bin/sh` still carries the pre-rename symbol
   `__schunix_tp`.
2. **The SchFS round-trip test** needs symlinks and hard links, which Git Bash
   cannot create, so it skips on Windows. **It has never actually run** — the
   one part of SchFS with no coverage.
3. **KVM.** A Ryzen box has SVM, so QEMU runs at native speed. Deliberately not
   the Makefile default: the suite's timings were set under TCG.

**PowerShell has no Fedora package**, and `tools/windows/bootcheck.ps1` is the
test suite. pwsh runs it on Linux fine; it comes from Microsoft's repo or the
GitHub tarball. Nothing else needs it.

**Never push.** There is no git remote and there should not be one until
Nexoniarz says otherwise — see [[nexoniarz-sharing-preference]]. "Push to git"
in this project means commit locally.
