I just had an epiphany — the whole point of the Linux Volume Manager is to abstract away this problem. If the Guix System were to be deployed entirely on one logical volume, then it should not matter what physical volumes are backing that. And all I need to start should be a single SSD, on which I would initialize a stack of appropriate volumes. Everything else can come in steps, as hoped for. Thank you for entertaining my questions. The responses did facilitate the aforementioned epiphany. Guix Community Member Marek Pasnikowski
