Bins live in /usr/local, so a later useradd no longer gets
~/.local/bin copies. systemctl --global enable the bakery
--user units (bake writes /etc/systemd/user/*.wants/, and
post-install + live-setup run the same enable) so first
login starts breadd, breadbox-sync, breadclipd, breadcrumbs,
and breadmill. Stock useradd -m copies skel (Hyprland +
bakery state). Rollback is still grub-btrfs.
BOS shipped zsh + a p10k skel .zshrc and Calamares' userShell was already
/bin/zsh, but two paths still defaulted to bash:
- /etc/default/useradd had SHELL=/usr/bin/bash, so any plain `useradd` (and
anything not going through Calamares) created bash users.
- bos-live-setup created the live ISO user with -s /bin/bash, so the live
session ran bash instead of the BOS zsh setup.
Ship /etc/default/useradd with SHELL=/usr/bin/zsh and create liveuser with zsh
so the whole distro — live and installed — defaults to zsh.
