Will removing [replacing] the top-level root be something that can/will be supported? I've asked in the past about this regarding an initramfs hook i maintain implementing system rollbacks, but I never really got a solid answer. For example, right now extlinux support booting btrfs, but _only_ from the top-level root. if i just had a way to "swap" the top-level root with a different subvol, i could overcome several problems i have with users all at once: ) users install their system to the top-level root, which means it is no longer manageable by snapshot scripts [currently] ) if the top-level root could be swapped, extlinux could then boot my snapshot? (i'm probably wrong here) "set-default" is not enough; i'm looking for a way to gain control over the system state when the system has been installed into the top-level root. currently, i have no way to manipulate/move/change it, because the top-level is essentially "immutable", or so it seems. thus it's not possible to support kernel rollbacks without manually syncing <snapshot>/boot to /boot. is there a solution to this that i'm missing?
