Three hardenings, each of which cost a field-debugging round-trip:
- Every mmcli failure now lands in the journal verbatim (create-bearer
and connect stderr were swallowed, making 'connect attempt N failed'
undecodable — no-service and interface-in-use looked identical).
- Connect attempts are gated on network registration (up to
IMS_REG_TIMEOUT, default 300 s): the 10x10 s window is shorter than
some carriers' post-boot attach (~2 min measured), so every attempt
could burn out before the network was even attached. The settled
modem/packet-service state is logged either way.
- Bearer ip-type is configurable via IMS_IP_TYPE in /etc/imsd.env
(default ipv6); the bearer find/reuse now matches ip-type too, so a
config change cannot silently reuse a stale bearer of the old type.
TimeoutStartSec grows 600->900 to cover the registration gate.
Tested on the FP6 dev phone (KPN): clean-state bring-up in 4 s;
gate + timeout path with modem disabled; per-attempt error lines on a
real contested-PDN failure (second ims PDN while one is connected);
idempotent reuse + REGISTERED (fresh) via systemd.
