Back to Manjaro. Reading <https://github.com/calamares/calamares/issues/533#issuecomment-971746992> (2021) alongside <https://en.wikipedia.org/wiki/Calamares_(software)>, I wonder why ZFS on root is not an option.

Maybe I'll never need to undo :-)
John Ramsden · zectl ZFS Boot Environment Manager for LinuxI’m happy to announce a new ZFS boot environment manager written completely from scratch in C - zectl.
In 2018 I wrote zedenv, a ZFS Boot Environment manager, I’ve taken what I learned from zedenv and added improvements in workflow, performance and reliability.
For a summary on what a boot environment manager is, and how it can be used see my previous post.
Why the Rewrite Link to heading I had been having misgivings about writing my original implementation in Python. At the time of writing there was no libzfs library interface for python and I wrote my own “wrapper library” - pyzfscmds - that simply called out to the zfs binary. While the wrapper has worked, it meant a lot of extra work was done parsing string output from zfs subcommands. Directly using the libzfs library allows for more robust code, significantly better performance, and error handling. I was considering porting the python tool to use py-libzfs, or writing it in C when the tool bectl came out for FreeBSD. Seeing bectl’s impressive implementation I was inspired to do the rewrite in C.
