Error - Impossible to create the root directory about packagist-mirror

[webysther]

Wow, shit. :(
This model is a replica of main mirror, i can't change this, but i can simulate this situation to create using symlink to more normalized structure, as you said.

Is possible to use docker? Look at this: https://github.com/Webysther/packagist-mirror-docker

With docker ins't possible to use UFS: https://docs.docker.com/storage/storagedriver/select-storage-driver/#supported-backing-filesystems

Maybe is that limitation you talk about https://docs.oracle.com/cd/E19120-01/open.solaris/819-2723/fsfilesysappx-5/index.html

Maximum Number of UFS Subdirectories
The maximum number of subdirectories per directory in a UFS file system is 32,767. This limit is predefined and cannot be changed.

Sorry @sdamo but packagist don't support today this file system, o recommend to use a modern one to solve your problem.
