Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to Boot ISO Files from GRUB2 Boot Loader
See also UEFI drivers that can read a bunch of other file systems (btrfs, ext2/3/4, HFS, ISO, NTFS, UFS/FFS, XFS, ZFS, etc):
* https://efi.akeo.ie
* https://github.com/pbatard/efifs
The UEFI spec specifies (ยง13.3) that firmware is only required to read FAT32/16/12, which is generally why your /boot/efi is VFAT/FAT32.

Is exFAT bootable?Can I boot WinPE with exFAT?
In theory you would still need a FAT32 efi 'stub' partition with the exFAT filesystem drivers which you have to load before loading the WinPE loader (bootmgfw.efi).

How do I configure the refind.conf and refind_linux.conf (and or config.yaml (for ZFSBootMenu)) files properly when installing Arch Linux with ZFS Native Encryption?
I am pretty sure that that I am doing something incorrectly with the configuration files for the rEFInd bootloader, but everything else should be correct. However, as I write this, I barely realized did I not use the following commands recommended from the "Usage" section from the aforementioned website where I downloaded the zfs_x64.efi driver file for rEFInd:

Grub vs Systemd-boot --removable question
I found the drivers here https://efi.akeo.ie/ . Which means, that any EFI bootloader able to load them will be able to use them. They are not for bootloader, but it is the firmware which will use them. As i said, i am little bit afraid that it will not work on any board as some manufacturers have pretty buggy firmware when talking about infrequently used features. Also i am bit unsure they will work with secure boot as they are gpl3 thus will be never signed by Microsoft and i don't know what UEFI requirements for drivers are in this regard.

Why use a bootloader? Just boot directly into a unified kernel image
Even for those using systemd-boot with custom efi drivers to provide functionality, it's worth noting that those drivers are being developed downstream of GRUB.
- Latest grub update on arch distros seems to cause boot issues
-
So why do so people still use GRUB?
I think you can also add btrfs filesystem support for sd-boot by including the EFI drivers for it on the EFI partition instead, from https://github.com/pbatard/efifs/releases I think. Haven't tried it myself though.

Fedora considers deprecating legacy BIOS
EFI doesn't actually mandate FAT for the system partition. The system partition can be any filesystem that the firmware supports.
Of course, pretty much all EFI implementations only support FAT, so it's a bit of a moot point; the only one I'm aware of that supports anything else is the one on Intel Macs, which also understands HFS+.
You can find a huge selection of EFI filesystem drivers at https://efi.akeo.ie/ but they're derived from GRUB and hence GPL, so don't expect the likes of American Megatrends to be bundling these any time soon.

PixieFail: Nine Vulnerabilities UEFI Implementations
> someone would have to pay a team of engineers to rewrite everything
A partial effort has already been made a while back: https://github.com/tianocore/edk2-staging/tree/edkii-rust
However, this uses uefi-rs, which is incompatible with TianoCore's BSD+Patent licensing, and therefore cannot be used as reference material, as the wiki page states: https://github.com/tianocore/tianocore.github.io/wiki/Tasks-...
More recent efforts have also been mentioned in the mailing list: https://edk2.groups.io/g/devel/search?p=recentpostdate%2Fsti...

[Guide] vTPM and Secureboot capability in a Proxmox-KVM [For Windows 11]
This involves recompiling OVMF with Secureboot and TPM capability and compiling swtpm and libtpms for emulating a TPM2, so quite some work to get it up and working. All of this assumes you are using the root user. The steps for compiling are roughly this guide: https://github.com/tianocore/tianocore.github.io/wiki/Common-instructions
