Add lib.optionals pkgs.stdenv.isLinux guards to roles that contain
Linux-only packages or services to prevent build failures on Darwin:
- communication: Guard Electron apps (element-desktop, fluffychat,
nextcloud-talk-desktop) that don't build on Darwin due to electron
build-from-source limitations
- kdeconnect: Guard entire config block since services.kdeconnect
requires D-Bus and systemd (Linux-only)
- sync: Guard syncthingtray package (requires Linux system tray)
- email: Guard systemd.user.services/timers (Darwin uses launchd)
- desktop: Guard Linux-only packages, services, and KDE-specific
configurations including gnome-keyring, systemd services, and
XDG mime associations
Implements bead: nixos-configs-tcu
Split mbsync channel into two: proton-main for bidirectional sync
(excluding Sent) and proton-sent for pull-only sync. This avoids
"far side refuses to store" errors from Proton Bridge rejecting
uploaded sent messages.
mu4e's refile moves messages between IMAP folders, enabling
cross-device sync via mbsync. notmuch tags are local-only.
- Switch from notmuch to mu/mu4e packages
- Auto-initialize mu database on first sync
- Configure mu4e with folder shortcuts and refile to Archive
- Add NixOS load-path for mu4e elisp files
Previously, the notmuch config applied the "inbox" tag to all new
messages regardless of which IMAP folder they were in. This caused
tag:inbox to return all 22k+ messages instead of just those in INBOX.
Changes:
- Use temporary "new" tag instead of "inbox" for newly indexed messages
- Add post-new hook that applies tags based on maildir folder location
- inbox tag now only applies to messages in INBOX folder
- Also adds sent, draft, spam, deleted, and archive tags based on folder
Set up complete email workflow in Emacs using:
- notmuch for email indexing and UI
- mbsync for IMAP synchronization from proton.johnogle.info
- msmtp for SMTP sending via port 25 with PLAIN auth
- systemd timer for automatic sync every 5 minutes
Configuration includes:
- New email role at home/roles/email with all mail tools
- Doom Emacs notmuch module enabled with saved searches
- Secure credential retrieval via rbw from Bitwarden
- Fixed systemd service PATH to access rbw-agent
- TLS/STARTTLS for secure connections
Email role enabled on nix-book (laptop-compact profile).
