Update: I managed to build wimboot after cherry-picking some patches.

Interesting. Sadly it only supports FAT32, NTFS and EXFAT with no Linux filesystems.
And Ventoy is free. It’s hard to argue with free.

Pretty much. I do have some releases, but considering Nix’s philosophy you probably should. Ventoy-CPIO should build fine, if the right toolchains and dietlibc are in PATH. Ventoy-boot relies on overlay mounts though, so it might not build within Nix.

On Linux installation is done through a series of scripts and vtoycli. I haven’t worked on that yet, but there’s build scripts there that should do the trick, but since they build it for multiple architectures, you’ll have to run just the stuff for your arch (probably x86_64).

sth like:

cd vtoycli/fat_io_lib/release
gcc -specs "/usr/local/musl/lib/musl-gcc.specs" -O2 -D_FILE_OFFSET_BITS=64 fat*.c -c
ar -rc libfat_io_64.a *.o
cd ../..
gcc -specs "/usr/local/musl/lib/musl-gcc.specs" -Os -static -D_FILE_OFFSET_BITS=64 -Ifat_io_lib/include fat_io_lib/lib/libfat_io_64.a *.c -o vtoycli_64
# Optional
strip --strip-all vtoycli_64

Focus on yourself first. I do have a Ko-Fi, but I don’t promote it much.

TLDR: There’s binaries instead of source code in the repo, which makes it hard to near-impossible to verify what it’s doing. And the instructions for building those is lacking.
