| echo '$start_precmd="$start_precmd; drvctl -d pchb0' >>
/etc/rc.conf.d/modules
That would want to be:
echo 'start_precmd=${start_precmd:+"${start_precmd}; "}"drvctl -d pchb0"' \
>> /etc/rc.conf.d/modules
or the new command could be prepended, that's a bit easier, as
cmd;
is legal sh code, but
;cmd
is not (hence all the crud above), so:
echo 'start_precmd="drvctl -d pchb0; ${start_precmd:-}"' >>
/etc/rc.conf.d/modules
should work, and both be the same when there is no existing start_precmd.
Or the way Iain Hibbert suggested, though I doubt there's much point wrapping
one single command in a function (if one wanted more than that one command,
perhaps testing something, maybe the "pchb0" string could come from a variable
set in rc.conf, and the command only be run if that var is set
modules_prestart()
{
if test -n "${bus_to_delete:-}"
then
drvctl -d "${bus_to_delete}"
fi
}
perhaps (but do think of a better name for the variable, and do set
it in rc.conf when required).
