Stage 6: server image with a console installer (0.4.0)
- server/ profile and build-iso.sh [desktop|server]; make iso-server, make qemu-server, run-qemu.sh --serial; login on tty and ttyS0 - das-server: SSH, chrony, NetworkManager/dhcpcd, Docker with Compose, nftables (closed except SSH, own table), fail2ban reading socklog, sshd without root passwords, Docker log rotation, tools - das-server-install: dialog installer in Ukrainian and English, or unattended with --config; GPT + Btrfs subvolumes, GRUB for UEFI and BIOS, serial console, SSH key with optional keys-only logins - das-install-common: mount-source and postinstall shared with Calamares - dsv: runit service manager (list, enable, disable, start, stop, restart, status, logs) with bash completion, also on the desktop - das-update split into a subpackage without GTK; the window and tray icon move to /usr/libexec/das/das-update-gui - das-snapper-setup enables dbus, which snapper needs - TODO: ISO size review with measured numbers and options Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
