From 22fb8b6147f7fb72407af80c36d5e99e4664fea2 Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Tue, 29 Sep 2026 07:27:13 -0300 Subject: Mount dials its peer at once and fails if none answers; a peer out of reach is said as `dial failed: ` Mount took any well-formed dial and nothing was found out until the first look through it, which then said `look: look: dial`. Mount now probes the peer (version, attach, its root) with the turn out, and fails its write, mounting nothing, when none answers; the dial errors read as words, `no answer`, `timed out`, `hung up`, and a look through a peer gone since names its path: `look: /n/peer/f: dial failed: no answer`.
