- das-helpers replaces the dsv package and adds shared functions in /usr/lib/das/helpers.sh (bilingual messages, sudo re-exec, prompts). - dsv new creates a runit service (command, user, directory, environment, svlogd log) and checks it stays up; dsv rm deletes one not from a package. - duser: list, add (installer groups, --admin, key, password), del, passwd, lock/unlock (key logins too), key add|list|rm, groups +/-. - dfw: allow/deny/status/reload for the tcp_ports and udp_ports sets of the inet das table, kept in /etc/nftables.d/dfw.nft and checked with nft -c. - dsys: info, hostname, timezone, locale, keymap. - xtools-minimal on both images. - nftables.conf no longer suggests restarting the nftables service: its finish script flushes the whole ruleset, fail2ban's and Docker's included. - das-server-install 0.2.0 mentions the helpers when it finishes.
