- Package Calamares 3.4.3 (Qt6, widgets UI) with xbps-src. - das-installer: Calamares setup for Void/runit with Das OS branding and slides. It copies the clean live image (live-base), builds locales and the host-only initramfs, rewrites kernels without sparse tails (GRUB 2.12 cannot read Btrfs holes at the end of a file), then removes itself. - das-snapshots: flat Btrfs layout (@, @home, @snapshots, @var_log, @var_cache_xbps), snapper with hourly snapshots via cronie, grub-btrfs menu, snapper-rollback, and a dracut module that boots read-only snapshots with a RAM overlay. - das-settings 0.2.0: start LightDM with the system locale. - Live image: GRUB, efibootmgr and the new packages; Das OS /etc/issue. - Build: wipe stale destdirs before building packages.
