Previously every new login retargeted ~/.ssh/agent.sock to its own
per-connection forwarded socket. That broke a multi-connection setup
when the most-recent connection (which 'won' the symlink) dropped:
all surviving connections' panes would point at a dead socket until a
fresh login from a surviving connection re-ran zprofile.
zprofile: only retarget when the existing symlink target is dead
(sshd unlinks the per-connection socket on disconnect, so [[ -S ]] on
the resolved path is a reliable liveness probe). First connection
seeds the symlink, subsequent logins keep using it.
ssh-agent-refresh: scan /tmp/ssh-*/agent.* for any live forwarded
socket and retarget to the first that responds to ssh-add. Lets the
surviving connection recover without waiting for a new login shell.
feat(zsh): recover Arch site-functions + HELPDIR after removing system zsh2026-05-22T09:41:24Zsommerfeldsommerfeld@sommerfeld.dev2026-05-22T09:41:24Zurn:sha1:6b7e057bd4fc2cbdffe5fc8b3095810db1ccf9e3
Switching to nix's zsh on the Arch host left two functional gaps the
Arch zsh package used to fill:
1. /usr/share/zsh/site-functions in fpath: pacman, paru, systemctl,
journalctl, flatpak, docker, kubectl, makepkg etc. drop their
completions there. nix zsh's compiled-in fpath doesn't include
/usr/share so we lose all of them silently. Added that path (and
vendor-completions for the VM's apt-installed completions) to the
existing fpath loop, guarded by [[ -d ]].
2. HELPDIR for the run-help / help-alias machinery: needed so 'help cd'
etc. find the per-builtin help docs. Pick the first existing version
dir, preferring nix-profile so it matches the running zsh version.
fix(ssh): stabilise forwarded ssh-agent socket across reconnects2026-05-22T09:41:23Zsommerfeldsommerfeld@sommerfeld.dev2026-05-22T09:41:23Zurn:sha1:159d69ddd122cfdb55d087d754d7472d42fa73ae
Forwarded SSH_AUTH_SOCK lives at /tmp/ssh-XXX/agent.NNN — a
per-connection path that disappears on disconnect, leaving every
long-running zellij pane (and its children: claude-code, nvim, …)
pointing at a dead socket. Reattaching after reconnect doesn't help:
the env was captured when zellij first started.
Fix: maintain ~/.ssh/agent.sock as a symlink, re-aimed at the live
forwarded socket on every login (zprofile). Export the stable path so
processes inherit a value that survives reconnects — git fetch /
commit signing keep working in re-attached zellij panes with zero
per-pane re-export.
Adds 'ssh-agent-refresh' helper for transitional panes still holding
the dead per-connection path: re-exports SSH_AUTH_SOCK to the stable
symlink and validates with ssh-add -l. Already-running children
(claude-code) must still be restarted since env is inherited, not
observed.
feat(zsh): enrich pacopt with reverse-optdep info2026-05-22T09:41:21Zsommerfeldsommerfeld@sommerfeld.dev2026-05-22T09:41:21Zurn:sha1:7212ed8f2e355856b456b0c83e8a1ebe5a62d71d
Promote pacopt from a plain alias to a function. In addition to listing
packages that remain installed solely as someone's optional dependency,
each package is now annotated with its parent(s) and the upstream
reason text from the parent's Optional Deps field.
Implementation is pacman-only (no expac): one awk pass over 'pacman -Qi'
builds a reverse index of every (parent, optdep, reason) edge in the
local DB, then per leaf package the index is filtered for matching deps.
