# Glue: where the store and one of its readers share a host, the reader waits
|
|
# for the store's container and `swarm-bao-pki`, which mints the leaf the
|
|
# reader logs in with.
|
|
#
|
|
# ONE PAIRING PER FILE — the store's container and PKI unit ← the readers that
|
|
# log in to it, and nothing else. The waits on the store's policy units are
|
|
# ./glue-bao-readers-policy-order.nix's.
|
|
#
|
|
# `Wants=` on `swarm-bao-pki`, not `Requires=`: a pki start that fails or is
|
|
# refused fails each requirer's job with `dependency`, which leaves the reader
|
|
# inactive rather than failed, so its `Restart=on-failure` never fires. Here
|
|
# the reader runs anyway; with its leaf still missing, its login exits 1 into
|
|
# ./lib/store-retry.nix's retries.
|
|
#
|
|
# ⚠️ Gated on BOTH the store and that reader being here. Off the store's host
|
|
# neither unit exists, and the reader's own start timeout bounds the attempt
|
|
# instead. On the store's host without the reader, setting
|
|
# `systemd.services.<reader>.after` would define a unit with no ExecStart, so
|
|
# each gate below restates the one the reader's own module puts on it. A
|
|
# reader whose gate changes must change here too.
