iso-patch.exe gains a new --ubuntu-to-vhdx mode that produces a fully
installed, bootable Ubuntu VHDX in one shot:
- vendored xz-embedded + custom ext4 writer + squashfs reader
- mounts the ISO, partitions GPT (ESP + Linux root), streams
casper/minimal.squashfs into a freshly-built ext4 rootfs through
a producer/N-decompress-worker/single-writer pipeline
- installs signed shim + grub from the ISO's pool .debs onto ESP,
writes a redirect grub.cfg pointing at the rootfs by UUID
- plants a defensive one-shot first-boot systemd unit that runs
grub-install + update-grub + AppSandbox guest setup (agent ELFs,
kernel modules, systemd units, wsl-mesa, wsl-deps, ldconfig,
no-sleep dconf, etc.) and reboots
linux_create_thread now spawns iso-patch with --ubuntu-to-vhdx
and a --stage manifest covering the full extras tree (reuses
stage_linux_agent_and_extras to populate a staging dir then walks
it). image_path is cleared post-build so the ISO isn't re-attached
to the runtime VM. ComPorts/com1 named pipe and the do_connect_rdp
window path are dropped (IDD is the only live display path now).
VideoMonitor stays unconditional (vmwp.exe crashes 0xC0000005
without it) — but with no ConnectionOptions/named pipe, matching
master.
JS frontend: "Installing Linux" branch added so the spinner label
no longer says "Installing Windows" for Linux VMs. Progress %
now tracks ingest fraction (n_processed / total_inodes) mapped
into 10..75%, with post-ingest phases at 82..99%.
