Print the command line before every external command (hdiutil, udisksctl,
wimlib-imagex, sgdisk, mkfs.fat, mmd, mcopy and so on) so the log shows
which command is running. Write the image straight to the output path
instead of moving it from the work directory, and remove a partial output
if the run fails or is cancelled.

QEMU's emulated USB CD-ROM reads the Windows ISO at a few MB/s. The script
builds a bootable FAT32 GPT disk image from the ISO, splitting install.wim into
install*.swm parts for the 4 GB FAT32 file limit, so the image can be attached
as an NVMe disk and read about 15 times faster.
It runs on macOS and Debian. The ISO has to be read as UDF: hdiutil on macOS,
mount -t udf as root on Linux, otherwise udisksctl, otherwise 7z extracts it.
A desktop session automounts the loop device that udisksctl creates, so the
existing mount point is reused when there is one. The image itself is built
without root.

Download the Ubuntu 26.04 LTS server cloud image (release 20260927) for
amd64 and arm64 from the TUNA, NJU and official mirrors, verified with the
pinned SHA256 checksums from the release's SHA256SUMS.

Each *_IMAGE_URL may now list several mirrors of the same file. When
aria2c is installed, the file is split across all mirrors with a single
connection to each; otherwise curl or wget tries the mirrors in order,
skipping mirrors that fail or return an empty response. A partial
download is only resumed with the same downloader and mirror list.
Fedora now defaults to the TUNA, BFSU and NJU mirrors. The Aliyun
mirror is not used because it rejects aria2c.

download.fedoraproject.org is slow from mainland China. The TUNA mirror
serves the same file (the pinned x86_64 SHA256 matches), and
FEDORA_IMAGE_URL still overrides the default.

Instead of a hard-coded file name, find the ISO in install-iso/ by
matching *Win*11*x64*.iso (case-insensitive), picking the highest
version-sorted name when several match. The QCOW2 path is derived from
the detected ISO name, falling back to an existing *Win*11*x64*.qcow2
in base-qcow2/ when the ISO is absent.

Debian/AlmaLinux/Fedora image filenames, URLs, and checksums were
hardcoded to arm64/aarch64 (for Apple Silicon macOS), which would
silently download the wrong-architecture image on an Intel/amd64
host. Detect the architecture from the host (uname -m), normalized
to arm64/amd64, with VM_IMAGE_ARCH as an override; the run-*.sh
scripts in the parent repo use the same override so both stay in
sync. amd64 keeps the previously pinned checksums; arm64 checksums
are still unpinned pending upstream publication.
windows11 is unaffected: it stays x86_64-only, matching run-windows11.sh.
