# DebloatMe - Fedora
# https://debloatme.com/fedora
#
# What this script does:
#   1. Runs dnf autoremove to clear packages nothing else depends on
#   2. Trims the systemd journal to a bounded size
#   3. Clears the dnf package cache
#   4. Lets you pick, from a checklist, which optional bundled apps to
#      remove (LibreOffice, a broader list of default GNOME apps) -
#      nothing is removed unless you select it
#
# Reads confirmation prompts from /dev/tty so this still works when the
# script is piped straight from curl (curl ... | bash).
#
# Written against Fedora Workstation (GNOME). Review this script before
# running it. Removing packages can have side effects depending on what
# you've built on top of them.
