+# The dracut patch is an issue uniquely bound to the fact that I'm using several
+# old-as-shit hardware RAID cards. Specifically the Dell PERC H200 and the Dell PERC
+# H310, both of which had their hardware drivers dropped in Cent8 (despite the drivers
+# being included in the upstream fedora kernel, but whatever). OS installation and the
+# process in this set of tasks is based off of this blog post:

+# TODO: Host the RPMs locally. The internet may never forget, but it's also never there
+# when you need it

+# NOTE: These tasks only need to be run on Cent8
