Annoying lag in “command not found”

[tdh@wont ~]$ jjj
Command not found.

Followed by an annoying lag. FC13 does not do this, but FC14 does.

It turns out there is a package called PackageKit-command-not-found and it is controlling this behavior.

[root@wont PackageKit]# pwd
[root@wont PackageKit]# diff CommandNotFound.conf CommandNotFound.conf.STOCK
< SoftwareSourceSearch=false
> SoftwareSourceSearch=true

And problem solved! I.e., I want to keep the other features of the package (for now), so this gives the solution with the least impact.
