I don't understand how this would differ from "kernel*", or why the backslash is necessary.

  • Hm. Not too sure then. Normally \* would mean you search for a literal asterisk and not the wildcard.

  • Seems like kernel* and "kernel*" give the same results. Perhaps yum passes this parameter to something else, so the * needs to be escaped first.
