Ian Wienand e42066d685 Cleanup yum downloading ... Using "yum --downloadonly" breaks the abstraction of "install-packages" because it downloads to the yum cache. It also acts funny if the package is already there. Add an argument to "-d" which is the directory to download to. dnf has "download" built in, and for the old case use yumdownloader which acts about the same. Ensure it is installed, since it comes in yum-utils. Also a slight cleanup of the getopt parsing so it's easier to have the required argument for -d Thus we can remove most of the stuff in 15-remove-grub. The check for centos6 and it's lack of grub2 is clarified. All the stuff about having to remove the package, purging the cache etc so yum gets the right thing is no longer relevant. The long section of commented out code at the end is also removed for clarity. I tested this with an F21, F22 & centos (6) build Change-Id: Id1e430e7d050a0b99ac449e2ea435e06cda1c4e6		2015-07-20 09:08:06 +10:00
