Pair (system_id, attr_key) will be unique?
I would suggest to not be unique.

I can image having attr_key:

people_having_access: msuchy
people_having_access: aprice

It will not mean change in WebUI, but in CLI we would have to extend to:

katello <user/pass> system_attribute delete --system-name="dudley" 
--name="cube number" --value="Chuck Norris"

While:
katello <user/pass> system_attribute delete --system-name="dudley" 
--name="cube number"
would ask if proceed if deleting more then one row unless --force is 
present on command line.

Add:
katello <user/pass> system_attribute update --system-name="dudley" 
--name="user" --old-value="Bruce Lee" --new-value="Chuck Norris"

And this command:
katello <user/pass> system_attribute update --system-name="dudley" 
--name="user" --new-value="Chuck Norris"
will refuse to continue if there is more then one attr_key "user" for 
"dudley".
