[pve-devel] applied: [PATCH pve-storage v4 2/2] fix #1611: implement import of base-images for LVM-thin Storage

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

with a small style follow-up, thanks!

create_base prints a warning (before this patch as well):

> WARNING: Combining activation change with other commands is not advised.

maybe we could get rid of that one? I guess it doesn't like `-an`
combined with other stuff..
