image: single dd-able system.img replaces vvfat+data-disk pair

2026-08-21T17:13:52Z

mksystem.sh stages one FAT32 image: \bzImage + \initramfs.cpio.gz (rsbl paths), \EFI\BOOT\BOOTX64.EFI (kernel direct by default, --chain for rsboot), \etc\motd.txt, empty \bin\cli + \bin\gui, seed files at the root. --gpt wraps it in a partition table for real USB dd targets. Makefile: run/run-gui/debug attach only system.img on ide.0 (vvfat lines deleted); stamp-based 'system' target rebuilds only when the kernel is newer, so runtime writes survive reboots; system-fresh wipes; inspect lists via mtools. build-image.sh/mkdisk.sh removed. test-disk.sh boots system.img with a throwaway OVMF varstore — a stale NvVars makes the firmware skip the \EFI\BOOT fallback. sendkeys.py pacing 50ms->250ms/1.5s: keystroke loss under host load corrupted typed lines (guest-side PS/2 ring overflow). Gate: test-disk PASS (fsck clean, file survives poweroff).

v0.5.5: crash reports go to a dedicated CRASHLOG USB stick

2026-08-02T13:21:34Z

The fault handler now writes crash.log to the volume labeled CRASHLOG (label-selected via fat::crash_vol), falling back to slot 0. On real hardware the boot USB may be unwritable, so a second stick labeled CRASHLOG survives the write; the shell auto-prints the previous crash report from it at next boot (read_crash_log resolves /disk//crash.log through the FAT path, since Disk nodes hold no cached children). - fat.rs: volume_label() + crash_vol() (no allocation) - fs.rs: write_crash_log targets crash_vol(); read_crash_log prefers the CRASHLOG disk node; drop now-unused first_disk() - mkdisk.sh: --label option - test-fault.sh: boots with a dedicated CRASHLOG stick (mkfs -F 32 -n CRASHLOG), verifies crash.log lands there and NOT on the ESP

fat: mount every FAT32 volume under /disk//, fix multi-entry LFN

2026-08-01T00:19:07Z

- fat.rs: VOL: Option → VOLS: Vec; try_mount() returns a Volume per disk and init() mounts every valid FAT32 volume found. Volume UID = sanitized uppercase label + 8-hex volume serial (e.g. RSDOS-5BD1E55F): unique per format, stable across reboots, human-recognizable, machine-parseable (^[A-Z0-9_]+-[0-9A-F]{8}$); cloned volumes get a -N suffix. Public ops take a vol index and select it (select_vol also picks the backing AHCI disk), matching the ahci::select pattern - fs.rs: /disk is now a plain directory whose children are one Disk node per mounted volume, named by UID; DiskInfo carries vol - LFN fix: entries are stored last-first on disk — both the writer (head-entry first) and reader (append in disk order) were reversed and cancelled out for ≤13-char names; multi-entry names (>13 chars) read back mangled (e.g. 'from-kernel.txt' as 'xt'). Writer now places seq=1 closest to the SFN and seq=N|0x40 first; reader places chunks by sequence number and trims at the first NUL. Verified with a 25-char filename round trip: kernel ls/cat correct, mtools shows the full LFN, fsck clean on both volumes - test-disk.sh: test file renamed to disk-test-.txt (>13 chars, exercises multi-entry LFN); UID discovered from the boot log; QEMU stdio redirected to a log file + EXIT trap so an orphaned QEMU can never hang a piped caller (it previously did, 400s)

scripts: automate the data-disk workflow (mkdisk / sendkeys / test-disk)

2026-07-31T23:56:12Z

- scripts/mkdisk.sh: create the FAT32 disk with mkfs.fat -C (the flag that actually creates the file — plain mkfs.fat fails on a missing path), accept M/G/K sizes, seed seed/ files via mtools; --fresh re-formats, --no-seed skips seeding - scripts/sendkeys.py: type lines into the guest via the QEMU monitor (US layout). Punctuation must use QEMU's named keys (minus, slash, dot, ...) — bare '-', '.', '/' are not valid sendkey names, and '-' is the modifier separator, so they were silently dropped before - scripts/test-disk.sh: full automated round trip — build, deploy, ensure image, boot headless QEMU, drive the shell (ls /disk, mkdir, echo >, cat, poweroff), then verify with fsck.fat (must be clean) and mtype (file content must have survived poweroff) - Makefile: make disk / disk-fresh / inspect / test-disk; run, run-gui and debug now auto-create a missing DISK_IMG; fix the stale comment (mkfs.fat without -C) - scripts/boot.sh: auto-create a missing DISK_IMG via mkdisk.sh - seed/: motd.txt + lines.txt seeded onto fresh images - Verified end to end: ./scripts/test-disk.sh --fresh passes
