Re: [HTCondor-users] START = (JobUniverse == docker)

[John M Knoeller <johnkn@xxxxxxxxxxx>]

Yes, just checking for WantDocker is sufficient.

START = WantDocker

I should remind people that it is almost always a mistake to compare an attribute to a Boolean using =?= in a start or requirements expression. 
Undefined behaves the same as false for matchmaking and =?=  will NOT evaluate to true if WantDocker is an integer rather than a Boolean,
because =?= is the *exactly equal* test.

TFM says 5 is for both vanilla and docker, so I did wonder. Would
"(WantDocker =?= True)" be sufficient though?
