comps.xml group and repo availability

[Joe Lawrence]

I was wondering about the behavior of yum and custom RPM groups in the
following scenario:

  comps.xml specifies a custom group of rpms
  createrepo -g comps.xml .
  setup /etc/yum.repos.d/file on machine
  yum groupinstall "my group"
  rm /etc/yum.repos.d/file

should I expect yum to still recognize "my group" as a valid RPM group
after removing the yum.repos.d file that provided it?

Thanks,
