+> 31 Oct 2020: sadly, due to legal obligations arising from a recent change in my 'real world' job, I must announce I am **standing down as maintainer of this project with immediate effect**. For the meantime, I will leave the repo up (for historical interest, and it may be of use to others); however, I plan no further updates, nor will I be accepting / actioning further pull requests or bug reports from this point. Email requests for support will also have to be politely declined, so, **please treat this as an effective EOL notice**.<br><br>For further details, please see my post [here](https://forums.gentoo.org/viewtopic-p-8522963.html#8522963).<br><br>With sincere apologies, sakaki ><

 ## Description
 **buildkernel** is a script that builds a Gentoo Linux EFI stub kernel which is suitable for booting from a USB key using UEFI (no additional bootloader required). It makes use of the initramfs creation tools (and early userspace **init**(8) script) provided by **genkernel**(8).
