Design 52: say the workstation's fstab line still mounts at boot until it is adopted, and can hold the boot 30 s

 2. **Assign `mounts` to the workstation, read-only.** Its `shares` is `library=<mount point>:ro`. Check
   `node-mounts.list`: the pair is armed, the share reads `armed` then `mounted` after a listing, and the
   files are there. Its unit pair takes the place of the unit generated from fstab.
+   **Until step 5 the hand-written fstab line still acts at boot.** The fstab generator still makes the
+   mount wanted by `remote-fs.target`, so at every boot the mount is started directly, not on access:
+   the module's `.mount` (which now carries the line's mount point) is pulled in at boot, can hold the
+   boot for up to its 30 s mount timeout, and fails when the home server is unreachable. The automount
+   protects only accesses after that. So step 5 follows soon after the share is seen working, and a
+   failed mount at boot in this window is expected, not a fault of the module.
   *Undo:* unassign `mounts`; its unit pairs go, and the fstab line is still there.

 4. **Read-write.** Change the grant to `rw` and the workstation's setting to drop `:ro`. Write one test
   file from the workstation, check its owner on the home server is the library's owner, and remove it.
   *Undo:* set both back to `ro`.
 5. **Adopt the workstation's library line**: `node-mounts.adopt` dry run, read it, then with

 6. **Adopt the ZFS property**: `node-nfs-server.adopt` dry run, then confirmed. The home network's
   export goes; the mesh's stays. *Undo:* `zfs set sharenfs=<the old value>` by a person, recorded as a
   hand-act.
