...Linux for Desktop opens new world...
...New opportunity for Korean OS in goverment PCs...

https://www.hancom.com/product/productGooroomMain.do

...Goorm OS provides secure, convenient, unique experience to desktop users...
...Goorm OS is based on debian linux...


Seriously?

I'm tired of fancy new Korea's OS platforms (K-OS) which is either 1) just another Linux distribution or 2) not Linux based but being so unusable

It is not Linux's job to stop you from shooting your foot. If you so choose to do so, then it is Linux's job to deliver Mr. Bullet to Mr. Foot in the most efficient way it knows.

(confession: I was torturing memory bus by fully cloning via virtio-fs (locally) instead of git.kernel{,testing}.org, before I learned how to do shallow clones and use reference git repositories)

Except kernel devs - kernel testing is too niche that modern CI services doesn't work well with it 😢

@vbabka tbh I'm not sure, but at least git repos that are regularly merged to linux-next shouldn't use that policy ;)

Anyway the policy seems to work quite well!

Hmm when running builds and testcases, my machine sometimes becomes very unstable and stuck for a while.

this causes some build/test failures because git clone or job submit timeouts are exceeded.

it's very annoying and I need to fix, but I couldn't find out why. I need to setup a monitoring system...

Here it is!

This is the first kernel repository that adopts "merge first and then drop if it's broken" policy ;)
