Heya,
I have a setup where I'd like to use two systems, one testing on Windows and one active on Linux use the same path for model and manifest to save storage.
The issue I have is: Linux deployment creates blob files with the name sha256:SHATHATHASBEENGENERATED and on Windows sha256-SHATHATHASBEENGENERATED this makes their filenames incompatible with each other and troublesome on Windows since any file with a : inside it is considered "non-existent"

Desired resolution:
A Patch where it'll be backwards-compatible with files that have : but the new default to be - so it will even work when the storage is on a NTFS or exFAT file system.

Thank you!
