- On btrfs, snapshots + zstd compression now just happen (no prompt); --snapper=no remains the explicit opt-out. - Vendor scripts/snapper-*.sh + config/snapper.actions from SysGuides/sysguides-snapper-fedora (MIT, upstream 0a28eb4) into vendor/snapper/ and install from there — no runtime clone of an external repo, and no dependency on exec bits (fixes the './install.sh: Permission denied' failure seen on the test VM). - grub-btrfs still cloned at runtime from Antynea/grub-btrfs with the Fedora config applied; everything else is local now.

# ----------------
|
|
# Creates a PRE snapshot before a DNF5 transaction begins.
|
|
#
|
|
# This script:
|
|
# - Generates a description using snapper-desc.sh
|
|
# - Stores the description and snapshot number in /run for later use
|
|
#
|
|
# The stored data is used by the POST script to:
|
|
# - Pair snapshots correctly
|
|
# - Improve snapshot descriptions (especially for GUI installs)
