Thanks for the pointer! Love the premise project. Just a few notes:
- a security focused project should NOT default to train people installing by piping to bash. If i try previewing the install script in the browser it forces download instead of showing as plain text. The first thing i see is an argument
# --prefix DIR Install to DIR (default: ~/.smolvm)
that later in the script is rm -rf deleting a lib folder. So if i accidentally pick a folder with ANY lib folder this will be deleted.
- Im not sure what the comparison to colima with krunkit machines is except you don't use vm images but how this works or how it is better is not 100% clear
- Just a minor thing but people don't have much attention and i just saw aws and fly.io in the description and nearly closed the project. it needs to be simpler to see this is a local sandbox with libkrun NOT a wrapper for a remote sandbox like so many of the projects out there.
Will try reaching you on some channel, would love to collaborate especially on devX, i would be very interested in something more reliable and bit more lightweight in placce of colima when libkrun can fully replace vz
Love this feedback, agree with you completely on all of it - I'll be making those changes.
1. In comparison with colima with krunkit, I ship smolvm with custom built kernel + rootfs, with a focus on the virtual machine as opposed to running containers (though I enable running containers inside it).
The customizations are also opensource here: https://github.com/smol-machines/libkrunfw
2. Good call on that description!
I've reached out to you on linkedin
What is the alternative to bash piping? If you don't trust the project install script, why would you trust the project itself? You can put malware in either.
That assumes you even need an install script. 90% of install scripts just check the platform and make the binary executable and put it in the right place. Just give me links to a github release page with immutable releases enabled and pure binaries. I download the binary but it in a temporary folder, run it with a seatbelt profile that logs what it does. Binaries should "just run" and at most access one folder in a place they show you and that is configurable! Fuck installers.
It turns out that it's possible for the server to detect whether it is running via "| bash" or if it's just being downloaded. Inspecting it via download and then running that specific download is safer than sending it directly to bash, even if you download it and inspect it before redownloading it and piping it to a shell.
The server can also put malware in the .tar.gz. Are you really checking all the files in there, even the binaries? If you don't what's the point of checking only the install script?
