VPN (PPTP): net.ppp0 работает лишь после перезапуска [исчезло само]

В один прекрасный момент я заметил, что сеть уже не поднимается при загрузке системы, хотя net.ppp0 не выдавал никаких ошибок при запуске. Тем не менее, сеть не работает, но после перезапуска net.ppp0 поднимается и работает без последующих проблем. Странное дело...

Имеется такой сценарий для поднятия VPN:

dns_domain_lo="RAMBOW"
config_eth0="dhcp"
dhcpcd_eth0="-t 60"
modules=( "dhcpcd" )

config_ppp0=( "ppp" )

dhcp_eth0="nogateway"

link_ppp0="pty 'pptp 10.0.0.138 --nolaunchpppd'"

username_ppp0='ИМЯ'
password_ppp0='ПАРОЛЬ'

pppd_ppp0=(
        "noauth"
        "defaultroute"
        "lcp-echo-interval 15"
        "lcp-echo-failure 3"
        "lock"
        "mtu 1300"
        "mru 1000"
        "nobsdcomp"
        "persist"
)

depend_ppp0() {
       need net.eth0
}

В логах ppp не могу ничего путного углядеть. Вот кусочек про последнюю загрузку:
