kraftkit: Running kraftkit without `sudo` runs much slower

Describe the bug

After running the hello-world application I tried to use kraft ps command. Running kraft ps takes much longer(2 seconds) than sudo kraft ps.

Steps to reproduce

git clone --depth=1 https://github.com/unikraft/app-helloworld.git;
cd app-helloworld;
kraft build --plat qemu --arch x86_64;
kraft run

kraft ps

Also, I think this is the same with all kraft commands. Running as sudo it much faster.

Expected behavior

Both kraft ps and sudo kraft ps commands should run at the same fast.

Which architectures were you using or does this bug affect?

x86_64

Which operating system were you using or does this bug affect?

linux/debian

Not if a common group is added that a user is part of and the group owns these resources. This is the idea behind chowning the runtime directory /var/kraftkit. Then multiple users can read and write to this common path.

By far the easiest solution here is to change --runtime-dir config value to somewhere owned by the user such that they do not have to use sudo.

I built kraft from staging and ran it.

If the user needs to fiddle with permissions manually on their machine the issue isn’t “fixed”.

I can’t reproduce this 😢

@nderjung has no chance to reproduce because his computer does not support more than one user

@antoineco can you investigate this when you have time?

@gabrielmocanu I noticed a similar behavior recently. Is kraft version also slow?

Nope. For kraft version I don’t see this problem.
