[WORKAROUND] dhcp al boot (rc.inet1)

[Mongo]

EDIT: in rc.inet1 ho portato il timeout a 30 secondi, e funziona. Ma questo vuol dire che c'è una condizione di corsa da qualche parte e sarebbe bello capire.
Ciao.

Salve,
ho notato che ultimamente, direi da dopo l'upgrade dei kernel packages, rc.inet1 non riesce più a negoziare un indirizzo dhcp al boot, mentre funziona se chiamato (restart) in seguito da linea di comando.
Attualmente si verifica sulla macchina con 14.2:
# uname -a
Linux bigfoot 4.4.29 #2 SMP Mon Oct 31 15:02:12 CDT 2016 x86_64 Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz GenuineIntel GNU/Linux
Suggerimenti?
Nel primo caso /var/log/messages riporta:

ciao, perchè non modifichi lo scriptino /etc/rc.d/rc.inet1 con un strace davanti all'invocazione di dhcpcd?

strace /sbin/dhcpcd -t ${DHCP_TIMEOUT[$i]:-10} ${DHCP_OPTIONS} ${1}

in questo modo il logger dovrebbe "parlare" di piu'
