Need to compare hashes between a stock ISO and one ~~flashed~~ booted by Ventoy (dd the latter to a file and check)

What does BLOB stand for?

This is a bit absurd. I really don't think this is as serious as some comments say. Also there is a comment from AUR package manager which explains more details. . And even the blobs in the first post there are source and build instructions in their respective folder.

I like multiboot. Used it back when I used Windows.
The Ventoy advertisements on Reddit looked too suspicious, so I never checked it out.

I just wish it had a real alternative. GRUB on USB doesnt support as much distros or windows.

It's a useful tool, but there is a security concern for anything not fully open source. You will have to weigh your risk factors, I doubt that it's any problem for most consumers or distro hoppers.

Best to keep an eye in case any new contributers arrive suddenly...

I've had too many issues with Ventoy that I'd rather just use fedora media writer or balenaetcher for when that doesn't work. I mean honestly it's a bit gimmicky, even if it's a cool concept. I believe Glim and some other options exist too

Is BLOB an acronym?
