[pve-devel] [PATCH v2 storage 6/7] introduce 'pve-storage-image-format' standard option for image format
Fiona Ebner

Wed Mar 5 11:49:22 CET 2025
The new 'pve-storage-image-format' standard option uses a simple enum
instead of a subroutine verifier. Since the 'pve-storage-format'
format that is replaced by it was used in pve-guest-common's
StorageTunnel, the format cannot be removed without a versioned
breaks.
