# Perform full package upgrade, and installs some basic packages not preinstalled.
#
# NOTE:
# - Originally written for WSL import of docker root filesystem of Fedora 33 and 34,
#   from Fedora Container Base image (with dnf) and Fedora Container Minimal
#   Base image (with microdnf). Updated for Fedora 35 - 37.
# - Must be run by actual root user, not by use of sudo from regular user,
#   (sudo is not installed by default in the Fedora Container Minimal Base image).
# - Interactive! Will prompt user before doing any changes!
# - Skips installation of documentation, by specifying --nodocs as command line
#   argument. Standard base image has this configured as default with
#   "tsflags=nodocs" in /etc/dns/dns.conf, but this is not supported by microdnf
#   so for the minimal base image it must be added on command line.
# - Using "update" command even if has been superseded by "upgrade",
#   because it wasn't until Fedora 34 that microdnf supported "upgrade" and
#   in both dnf and microdnf "update" still works as an alias for "upgrade"!

# forced UTC as timezone.
# WSL automatically sets the timezone of the distro, it creates the /etc/localtime
# symlink to the proper file under /usr/share/zoneinfo matching the configured
# timezone in Windows. To ensure this works as intended, we reinstall the tzdata
# package if zoneinfo files are still missing - if the upgrade command above
# found and installed a new version of tzdata then it will already have
# installed zoneinfo files and reinstall will not be necessary after all.
