3 years ago "this1" is a script I wrote. "this2" is someone else' script.
333:350 creates a systemd service file to import bpool using /etc/zfs/zpool.cache. The "4.9" tag refers to the instructions at https://openzfs.github.io/openzfs-docs/Getting%20Started/Debian/Debian%20Buster%20Root%20on%20ZFS.html at the time I wrote the script. I see the instructions have now been renumbered and that is now "11"
"initial" is a minor convenience to install/start an SSH server in the live environment in case you want to SSH in to perform the rest of the procedure.
"post-reboot" is similarly a convenience to perform the post reboot operations that I usually need to do.
"env.sh" sets up environment variables that control how the script operates, in other words, does it do whole disk, selected partitions or previously prepared pools. "env.sh" is the default file name for these. If you look in the .../testing directory you will find a bunch of variants of this that configure for particular combinations of configurations. I find it convenient to choose one of these as a starting point when getting ready to install. For example, if I were installing dual boot to selected partitions and using ZFS native encryption I would
- create the partitions for bpool and rpool
- identify the existing EFI partition
- copy part.std.zfs_enc.sh to my.env.vars.sh and modify the environment variables to match the target setup. Be aware that these scripts are used for testing and in addition to setting up the environment variables will also create the partitions and/or pools so you will want to modify or delete those.
- copy the scripts to the live environment on the target.
- run the main script in the target with "install_Debian_to_ZFS_root.sh my.env.vars.sh"
Since I wrote the script, ZFS now supports zstd compression and I would use that instead of lz4.
Does this answer your questions?
best,

First of all, thanks for the excellent script. I'm trying to do ZFS root on Debian Bullseye, by running the script line-by-line, which will be a dual boot with Win10. There are two scripts this1 https://github.com/HankB/Linux_ZFS_Root/blob/master/Debian/install_Debian_to_ZFS_root.sh and this2 https://raw.githubusercontent.com/hn/debian-buster-zfs-root/master/debian-buster-zfs-root.sh
- which script to use?
Appreciate your clarification on some steps in this1 https://github.com/HankB/Linux_ZFS_Root/blob/master/Debian/install_Debian_to_ZFS_root.sh, from line 333 to 350. I guess these are ZFS related commands to import ZFS's bpool. It is a lot clearer in your script compared to Nourlin's blog https://noulin.net/blog/linux/2021/06/26/setting-up-root-on-zfs-in-debian-bullseye.html
Do I need to run initial https://github.com/HankB/Linux_ZFS_Root/blob/master/Debian/initial.sh, then this1 https://github.com/HankB/Linux_ZFS_Root/blob/master/Debian/install_Debian_to_ZFS_root.sh and finally post reboot https://github.com/HankB/Linux_ZFS_Root/blob/master/Debian/post-reboot.sh script? The env.sh usage is not that clear, Thanks.
