Claude 9e886ff9a7 Fix CIFS mount error(79) caused by missing nls_utf8 kernel module
The keyutils fix alone didn't resolve it — confirmed live with keyutils
already installed, the same error persisted. Root cause: the hardcoded
iocharset=utf8 mount option requires the kernel's nls_utf8 module, which
some kernels don't ship at all (confirmed live: `modprobe nls_utf8` on a
stock Ubuntu 6.8.0-137-generic VPS kernel returns "FATAL: Module
nls_utf8 not found" — not loadable, not built in). Every such mount
fails with errno 79 (ELIBACC) regardless of credentials, which is why
this recurred identically after the keyutils fix.

Both vpn-data-mount.sh and mount-network-drive.sh now probe with a
harmless `modprobe nls_utf8` before adding the option, and mount without
it (falling back to the kernel's build-time nls_default) with a clear
warning if the module isn't available, instead of hard-failing.

#!/bin/bash
# services/vpn-data-mount.sh — mount existing SMB shares from a
# NetBird-connected home box, with SSH-key bootstrap automated.
# Part of the modular post-install system (sourced by setup.sh).
#
# Can also be run standalone on any machine:
# sudo bash vpn-data-mount.sh
# (No Docker needed — this only touches SSH and /etc/fstab)
#
# Unlike most services here, this is repeatable by design: different
# services can have data on different home boxes, so this asks for a home
# box IP every time and can be re-run any number of times, once per
# home-box you want to pull shares from. It's the multi-instance pattern
# from CLAUDE.md generalized from "N instances of one app" to "N
# independent mounts" — there's no single install directory to gate on, so
# state lives in /etc/fstab itself (tagged entries), same as
# tools/mount-network-drive.sh.
#
# Deliberately READ-ONLY on the home box's Samba config — this tool never
# writes to smb.conf, never installs Samba, never creates or resets a
# Samba account there. It only (a) bootstraps passwordless SSH if needed,
# then (b) reads the home box's existing smb.conf over that SSH connection
# to list whatever shares are already configured there, so you can pick
# one or more to mount. Set up the actual share(s) on the home box
# yourself, the normal way (or with tools/mount-network-drive.sh's own
# guided flow, run there). An earlier version of this tried to fully
# provision Samba remotely too — reversed per direct request, and it had
# also caused real damage in practice (a section-removal bug that deleted
# unrelated shares on a real box) that a read-only tool can't repeat.
#
# Assumes the home box is Linux and reachable over a NetBird IP — this repo
# doesn't set up the home box's side of NetBird (that's a separate machine,
# possibly not running this repo at all).
#
# SMB chosen over NFS/SSHFS deliberately: NFS is marginally faster for
# Linux-to-Linux but SMB isn't a "huge" difference for normal use (media,
# docs, moderate datasets — the gap shows up mainly on many-small-files
# workloads). SSHFS was ruled out because the VPN tunnel already encrypts
# everything — SSHFS's own SSH-layer encryption on top of that is pure
# redundant overhead for no added security, and it's the slowest and least
# robust (FUSE reconnect quirks) of the three for an always-on mount.
#
# Mounts use real Samba credentials (a username/password you provide for
# an account that already exists on the home box), stored locally in a
# root-only credentials file, same convention tools/mount-network-drive.sh
# already uses — never guest access.
#
# "mount error(79): Can not access a needed shared library" is NOT a
# credentials problem, guest-vs-authenticated problem, or a mislabeled
# ENOKEY — errno 79 is literally ELIBACC, and mount.cifs prints glibc's
# literal strerror() text for it. Confirmed live: this recurred identically
# with a real Samba account and a verified, correctly-captured password
# (see the read()/IFS note above — that was a real bug too, just not this
# one), and again after keyutils was already installed — so it's not that
# either, at least not on every host. Two independent real causes share
# this exact errno/message, both fixed defensively below:
# 1. `keyutils` missing on the client. cifs-utils hard-depends on the
# libkeyutils1 *library* but only Recommends the keyutils *package*
# (/sbin/request-key + /etc/request-key.d/*.conf, what the kernel's
# upcall actually invokes) — minimal cloud images that disable
# install-recommends silently skip it.
# 2. The hardcoded `iocharset=utf8` mount option needs the kernel's
# nls_utf8 module. Confirmed live on a stock Ubuntu 6.8.0-137-generic
# VPS kernel: `modprobe nls_utf8` → "FATAL: Module nls_utf8 not found"
# — not loadable, not built in, just absent from that kernel build.
# Every mount asking for that codepage fails with errno 79 regardless
# of credentials. `_vdm_mount_local` probes for it with a harmless
# `modprobe` and only adds `iocharset=utf8` if it actually loads;
# otherwise it warns and mounts without it (kernel falls back to its
# build's nls_default — fine for ASCII-heavy filenames, the common
# case for a home-data share; non-ASCII filenames may not round-trip
# perfectly on a kernel missing this module, which is a kernel
# limitation this script can't paper over further).
