Related issue: Resolves #56443

This PR added nixos support; however, nixos doesn't follow a traditional FHS and needs to also delete the nix-store for system directories.

Summary by CodeRabbit

  • System Cleanup
    • Cleanup now includes the system package store when writable access can be verified. If access checks, remounting, or confirmation fail, the store is left untouched. The store is processed last in the cleanup sequence. Existing handling for other system locations remains unchanged, so their deletion flow continues as before.

Walkthrough

The Linux wipe script adds /nix/store to the deletion paths when the directory exists. It checks the mount options and attempts a read-write bind remount when the store is mounted read-only. If mount inspection, remount, or confirmation fails, the script skips deletion of the store. Other deletion paths retain the existing network-filesystem check.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 1a8c4

The Nix store is wiped after the other system paths, preserving the tools needed to complete those steps. No actionable merge-blocking risk remains.

29 of 31 checks passed
allenhouchins added a commit that referenced this pull request Nov 6, 2026
**Related issue:** NA

Adds Fleet's November 2026 newsletter
(`articles/newsletter-2026-11.md`), which covers October 2026. It
publishes at `fleetdm.com/newsletters/newsletter-2026-11`.

- **Email subject line:** `Fleet news: November 2026`
- **Category:** `newsletter`, singular, which the website build accepts
(#52120). No website changes are needed.
- **Author:** Aube Paul (`robinedev`), matching the September and
October issues.

## Open questions for reviewers

- **New "📺 Fleet Virtual Summit" section** for the November 10 LinkedIn
Live event, placed before workshops. Keep it or fold it into the
workshops section. If it stays, it's a new entry in the newsletter's
section emoji table.
- **The roadmap preview is linked even though November isn't a quarter's
first month.** The October preview published October 13, after the
October issue went out, so readers haven't seen it in the newsletter
yet.
- **Article and guide picks are editorial**, not based on traffic
numbers. Reorder them if you have analytics. There were no case studies
in October.
- **The community section has one post, and it's personal.** Henry
Stamerjohann's MacSysAdmin talk. Fleet's company-page post about the
"Apple in the enterprise" research is another option, but it repeats the
research article in "Worth reading." No engagement numbers were
available.
- **Community contributors with five or more merged PRs in October:**
Prajwal Janbandhu (8, in the thank-you line), Michael Alt (6,
highlighted), Dhvanit (6, returning, not named), and Shreyash Agare (5,
returning, not named). Confirm none of them is a contractor whose
account isn't in the org.
- **Several first-time contributors only edited the handbook.** None
appear in Fleet's Slack, so they stay in the thank-you line.

## How each section was sourced

- **Shipped:** the Fleet 4.93.0 and 4.94.0 release articles,
cross-checked against tagged releases. The three highlights are macOS
patch notifications (Premium), Android zero-touch enrollment (Premium),
and self-service configuration profiles (not Premium), so the section
isn't all Premium. Patch releases 4.93.1 and 4.93.2 are covered by the
"See every release" link.
- **Planned:** the release planning board (view 10, filtered to
milestone 4.95.0), not the milestone fallback. There are 22 stories, all
assigned. 5.0.0 is due December 4, so November holds one release.
- **Workshops:** fleetdm.com/workshops, with the next five after the
send date.
- **Community contributions:** PRs merged in public `fleetdm` repos in
October by authors outside the `fleetdm` org, minus bots.

## Left out on purpose

- **"Windows: force standard account"** was in the planned section in
both September and October and hasn't shipped. It's not on the 4.95.0
board, so it isn't mentioned a third time.
- **Multiple versions of the same App Store app** is named in the 4.94.0
release article's title, but the article marks it as moved to 4.95. It's
listed under "Also on deck" instead of "shipped."
- **Amsterdam workshop (November 3):** past by the time this sends.
- **Fleet staff or contractors whose accounts aren't in the org:**
@TraiLynne and @thomcrowe. Both are confirmed in Fleet's Slack.
- **Other October content:** the warehouse inventory article and
Retriever guide, the PHP2Shell and eMudhra pieces, and every `industry
news` article. The routine doesn't feature that category.

## Testing

- [x] Confirmed the markdown passes the website build's metadata checks:
required meta tags, ISO `publishedOn`, description at 139 of 150
characters, `category` set to `newsletter`, H1 matching `articleTitle`,
and no Vue-template braces.
- [x] Verified all 54 fleetdm.com, GitHub, and Eventbrite links return
200. LinkedIn returns 999 to automated requests, so the profile links
come from the handbook and the post link was opened in a browser.
- [x] Checked the copy against Fleet's content style: no em dashes,
sentence-case headings, Oxford commas, and Fleet Premium labels carried
through from the release articles.
- [ ] QA'd all new/changed functionality manually
