I’m in the process of migrating my custom kernel to Arch/EOS, currently, this is 5.8-rc. As Manjaro uses a custom `mkinitcpio`, some changes to the PKGBUILD were necessary. However, I left Manjaro’s extramodules handling in place. From what I can tell, EOS doesn’t use extramodules, and relies on dkms for out-of-tree modules, is that correct? If you want to have a look at it, and maybe even compile and install it, here you go: [https://github.com/torvic9/linux58-vd/tree/arch](https://github.com/torvic9/linux58-vd/tree/arch) (Note: it still says “for Manjaro”, haven’t updated that part yet) (Note 2: virtualbox host modules do not work yet with 5.8) Any sort of feedback is welcome! ---

I really think you should reconsider the name for your kernel. 😉 ---

Just tested this with `acpi_call` module. Both dkms and extramodule work correctly. However dkms does not work if the kernel is compiled with Clang, but this is a known problem: `CC=clang` has to be passed to make in `dkms.conf`. So it seems that both ways are possible, which is good news 🙂 * * * @jonathon: correct. * * * > [@dalto](#): > > I really think you should reconsider the name for your kernel. Why? 🙂 ---

That is probably the last thing that comes to my mind when I think of ‘vd’… Actually never heard of that term, despite having watched all of House MD 🙂 (Hint: it stands for ‘Victor Development’, quite cheesy isn’t it?) ---

🤣 Also it can potentially be spread and adopted as fast as vd, which should be good! 😆 P.S. @dalto Haven’t seen this one coming too ---

vd is rather an old term, the new term is [STD](https://www.healthline.com/health/sexually-transmitted-diseases) So don’t use that one either. This is starting to sound like a class I took in high school. 🙉 Just for historic reference, I graduated from high school in 1968. Yah, hippies, Vietnam War, Timothy Leary, and a lot of other weird stuff.

Seriously, knowing it’s facebook standard…you just can’t make that up! 😆 I think i need to check up on doctor, just as you guys, i have about 1000 zstd packages on my system now, not looking good 🤣 Of course they unpack and transmit on your system very fast, but i’m not sure i’m fan of Zuckerberg’s std 🤣 ---

Given that this kernel supports ZSTD kernel and initram compression, I’d be very careful… 😅 ---

see this - there is also some patch for compression zstd [https://github.com/torvic9/linux58-vd](https://github.com/torvic9/linux58-vd) may be missing patches zstd and also update mkinitcpio.conf if you want use zstd ---
