Re: system hangs at boot - LUKS /home/ problem(?)

[Fulbert <fulbert@bluewin.ch>]

I forgot to mention : LUKS version 2 with PBKDF: argon2i. I remember reading
that guix supported LUKS2 except for /boot… but I might be wrong. At 
least it
has worked for month on my computer until guix d5f857a (22 mar 2024).

So, new question, do I have to convert to LUKS1 ?
