# To determine what dconf keys and values to use, you can run `dconf watch /`
# in a terminal as you make changes in settings or tweaks.  You can also use
# `dconf read <key>` and `dconf write <key> <value>` to experiment with various
# settings.  The dconf-editor application is also useful for exploring various
# keys along with their descriptions.

TLDR:

• yum clean all == clean most
• rm -rf /car/cache/yum/* == really clean everything

From the man page:

Note that these commands only operate on files in currently enabled
repositories. If you use substitution variables (such as $releasever) in your cachedir configuration, the operation is further restricted to the current
values of those variables.

How I switched from mdadm to btrfs

After reading [this Ars Technica article][1], I decided that I wanted to start using btrfs on my home fileserver. It had been running for a few years with an mdadm raid-10 array, formatted with ext4, holding about 3.4 TB of data. I figured I would take advantage of some of the special capabilities of btrfs to perform the conversion in place. After some research, I formed my basic plan.

• backup data to external drives
• remove two of the drives from the mdadm raid-10
• configure those two drive with a btrfs raid-0 filesystem
• copy the data from the degraded mdadm raid-10 to the new btrfs raid-0
• completely deactivate the mdadm raid-10
