#  1) Helps you select and mount a drive/partition at boot (via /etc/fstab).
#  2) Installs Plex Media Server from a local .deb file in your ~/Downloads folder,
#     and opens port 32400 via UFW.
#
# If the user selects 'exfat' as the file system, we do NOT install exfat-fuse or exfat-utils,
# assuming the Ubuntu-based system already supports exFAT natively (e.g., Ubuntu 20.04+).
