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.

PSA: upgrade your LUKS key derivation function
People should stop using plain passwords to protect data and switch to something better.oster/ + Yubikey

[Boot error] Initramfs unpacking failed after updating to 6.0.1
Change from mkinitcpio to booster. It's faster and produce smaller images.
-
Dracut or Genkernel?
Neither, use booster.
-
Booster initramfs release 0.9 got ZFS support
Booster is an initramfs - a type of software that runs early during the boot process and helps to setup system, e.g. perform disk unlock, load extra drivers, setup ZFS filesystem, and so on.
-
You can end up without any kernel to boot if your computer crashes during a pacman update
I don't have high hopes that this will change in mkinitcpio, but perhaps you could bring it up with booster (which copied the mkinitcpio hooks and removal scripts)
-
Is There Something To Improve to my arch install "Guide"?
This is my personal preference, but consider switching to booster.
-
What is your current setup? Bootloader, filesystem, partitions, etc.
initramfs: booster - TPM2 support, way faster than mkinitcpio, autodiscovering root partition
-
Complex Issue:
Note I'm using booster, so assuming you're using the default mkinitcpio you probably want /boot/initramfs-linux.img. Also, don't forget to modify if your ESP isn't mounted at /boot like mine.
-
Systemd 250 released
Booster initramfs generator supports TPM, Yubikey and Network binding so you can easily protect your data using the strategy you want.

Booster dont loads with efistub
GPT table detection has higher priority at booster code. But for some reason it does not identify your partition table as GPT. Filed a github bug for it https://github.com/anatol/booster/issues/119

Can I boot an encrypted system by pulling the key from another PC?
Have a look at clevis and tang. These allow you do have one server - which could be your remote you want to pull from - to be source of the LUKS decryption on the system using tang.
-
PSA: Upgrade your LUKS key derivation function
I found that running tang[1] at home and needing to decrypt that box (can be a Pi or whatever) requiring a complex passphrase is very sufficient. You can even just unplug it at night if it makes you sleep better.

How to mount LUKS encrypted USB storages (and HDDs inserted to hot swappable drive bay) automatically when connected? The machine is running headlessly, does not have desktop environments installed.
There are 3 ways to unlock a volume in a headless environment: - use a keyfile, located on an already available volume - use your device's TPM and utilize systemd-cryptenroll - use Clevis/Tang to unlock volumes remotely
-
is possible to encrypt disk without asking for password on boot?
This is why on headless servers you use tang (ideally, multiple tang servers)

Tang on OPNSense
Sharing my notes on running a Tang server on OPNSense, in case it is useful for somebody else.
-
PSA: If you have a LUKS encrypted system and a TPM2 chip, you can put it to good use
We use clevis against multiple tang servers to provide Network Bound Disk Encryption (NBDE). It's possible to also use TPM2 but it's easier to use multiple tang servers (requiring more than one server to decrypt) in the datacenter.

A lot of questions about Self hosting :)
For automating unlocking of encrypted drives, look into tang . Here is a red hat guide on setting it up. You will want to be running this on another device on your network, i run it on my router with openwrt since its a local device thats on 24/7. Basically it will unlock your disks as long as your server is on your network, so if your machine or drives are stolen or removed from your network they will just be encrypted as usual. Obviously use a strong encryption password.
-
Systemd 250 released
There are other ways to bind data, e.g. "network binding" with Tang server.

Best Evil Maid prototcol for Linux?
I wonder if https://github.com/latchset/clevis and https://github.com/latchset/tang (complementary projects) will help here.

Luks Root Encryption
Yes you can, using either Mandos or Clevis and Tang. https://www.recompile.se/mandos https://github.com/latchset/clevis https://github.com/latchset/tang. Basically on boot the server gets the key from another(s) servers. You could use a hidden raspberry pi for example.
What are some alternatives?
u-root - A fully Go userland with Linux bootloaders! u-root can create a one-binary root file system (initramfs) containing a busybox-like set of tools written in Go.
clevis - Automated Encryption Framework
yubikey-full-disk-encryption - Use YubiKey to unlock a LUKS partition
sedutil - Use sedutil for setting up and using self encrypting drives (SEDs) that comply with the TCG OPAL 2.00 standard. This includes the requisite pre-boot authentication image.
