I would like to note here that the issue with the symlink as expertly described by Thulium-Drake was not resolved with version:
katello-4.1.3-1.el8
Although I would like to also note that given the following setup:
-Foreman host OS: Rocky Linux release 8.4 (Green Obsidian)
-Foreman Smart Proxy OS: Rocky Linux release 8.4 (Green Obsidian)
-Synced content: Rocky_Linux 8 (AppStream + BaseOS)
-Provision target host: Rocky Linux release 8.4 (Green Obsidian)
The syncs I performed were:
“Sync now” from a Rocky repo
“Optimized Sync” from the Foreman server to the smart proxy using an “On Demand” Download policy
I was able to kickstart a test host from the smart proxy with no issue.
Here is hoping the symlink fix makes it into the katello 4.2 release
