#
# zmrepo_mkdirs.sh - (Re)create the directory tree the RPM build workflows
# rsync into on zmrepo.
#
# The build-rpm-packages*.yml workflows publish with easingthemes/ssh-deploy
# using rsync args "-rltgoDzvO" (no --mkpath), so rsync will NOT create the
# parent directories of the target. If the tree is deleted, the deploy step
# fails. This script recreates the full tree.
#
# Target layout (matches workflow TARGET: rpm/master/<family>/<releasever>/<arch>/):
#
#   <root>/rpm/master/el/10/{x86_64,aarch64}/
#   <root>/rpm/master/el/9/{x86_64,aarch64}/
#   <root>/rpm/master/el/8/{x86_64,aarch64}/
#   <root>/rpm/master/fedora/45/{x86_64,aarch64}/
#   <root>/rpm/master/fedora/44/{x86_64,aarch64}/
#   <root>/rpm/master/fedora/43/{x86_64,aarch64}/
#
# Usage:
#   # Run directly on zmrepo (root defaults to the SSH user's home, ".")
#   ./zmrepo_mkdirs.sh
#
#   # Run from anywhere over SSH (uses the same host the workflow rsyncs to)
#   ./zmrepo_mkdirs.sh --ssh user@zmrepo.example.com
#
#   # Override the repo root and/or branch
#   ROOT=/srv/www/zmrepo BRANCH=master ./zmrepo_mkdirs.sh
#
# Options:
#   --ssh <dest>   Create the tree on a remote host via ssh instead of locally.
#   --createrepo   After making dirs, run createrepo_c so empty dirs are valid
#                  yum repos (clients error on a repo with no repodata).
#   -n, --dry-run  Print what would be done without doing it.
#
