File name too long

[cjunge]

Just updated to Symfony Flex 1.17.2 and trying to run composer recipes I keep getting:

$ composer recipes

Xubuntu 21.04, ext4, composer 2.1.12

The cache-key is generated from the URL, which needs to be shortened.

$ composer recipes -vv

As a co-worker just pointed out to me, this is an ecryptfs limitation (encrypted home folder), rather than ext4.
