debian - Linux Runlevel 1: start programm -

i'm trying automatically start process when come in runlevel 1 init 1. it's watchdog has send life signal time hence in runlevel 1 too! when runlevel 1 entered each process killed , scheme switches runlevel s. tried tell linux start process update-rc.d -f watchdog 99 1 s .. resulting entries in /etc/rc1.d/ , /etc/rcs.d/ are:

/etc/rc1.d/:

. . . s30killprocs -> ../init.d/killprocs s90single -> ../init.d/single s99watchdog -> ../init.d/watchdog . . .

/etc/rcs.d/:

. . . s01glibc.sh -> ../init.d/glibc.sh s02hostname.sh -> ../init.d/hostname.sh s99watchdog -> ../init.d/watchdog . . .

a ps ax after runlevel 1 entered sadfully doesn't homecoming watchdog process. have start manually.

the scheme i'm working on debian gnu/linux 5.0 debarm (embedded). hints or solution? give thanks you.

as said here:

run level 1 known 'single user' mode. more apt description 'rescue', or 'trouble-shooting' mode. in run level 1, no daemons (services) started.

you have several options around limitation:

don't utilize runlevel 1, not meant for start watchdog on login (if valid option), e.g. .bashrc.
