Upgrade from git 7.3-stable to 7-4-stable failed with bad gitlab.yml
The gitlab.yml file produced by this recipe failed with the latest yaml. In particular, the ldap section had the 'enabled: true' indented less than the 'host: ...' line which the latest yaml rejected. Manually correcting the yml file allowed the upgrade to proceed, but with manual operations as the recipe would overwrite the corrected yml file.
