[pve-devel] [PATCH v2 storage 1/5] postinst: move cifs credential files into subdirectory upon update

[Fabian Ebner <f.ebner@proxmox.com>]

and drop the compat code.

Signed-off-by: Fabian Ebner <f.ebner@proxmox.com>

Changes from v1:
    * make sure to create the /etc/pve/priv/storage directory which might not
      exist yet
    * always print info when a file was found
    * use variable for target path
    * use mv
    * removing the helper needs to wait until 8.0
