Yes, those were set to get around grub wanting to give an interactive prompt to decide what to do about the config file. From what Andy and I discussed earlier on IRC, it should be ok to remove them since he has 'etc/default/grub.d/99-ci-eng.cfg' getting created and used, but I'm working on testing it now using this branch.
