[pve-devel] [PATCH installer v3 0/4] add check/rename for already-existing ZFS rpool

[Aaron Lauterer]

tested this series more thoroughly and checked with an existing root 
pool all 3 install options:

* TUI
* GUI
* auto

Worked well in 3 cases to rename.

One oddity seems to be if we cancel the rename in the TUI installer. it 
jumps to 100% and stays there and I then need to manually abort. Jumping 
to a "setup cancelled" box that we confirm before quitting would be 
nice. This is how the GUI installer handles it.

Otherwise, besides this and a tiny nit in patch 4, consider this:
