@vcaputo could you take a look at this? Related to coreos/coreos-overlay#2106

Looks like it was introduced in 9184ca4 since parse_percent checks the value is in the range [0,100]. Looking through the man pages, it appears the CPUQuota is the only place where values >100% are used. Not sure if a "parse_percent_unbounded" should be introduced or just revert the change in that one spot.

I've tested using a parse_percent_unbounded function, which seems to work for me. The PR is #3886.

Huh, I only get notified on my personal email for this project, didn't see my mention til now. I believe dm0 is working on this.
