Hi All,
I’ve set up wireless access point via hostapd and it is working smoothly. I’ve created a simple init script (see below) in /etc/init.d/ and used chkconfig, insserv and/or yast (trying many different combinations of commands) to activate the script for certain runlevels. When ‘service hostapd start’ is called by root, the service activates as normal.
However, the service will not automatically start at boot.
According to boot.msg, the service is being started before the $remote_fs psuedo-service is brought up. Even if the ‘required-start’ field is set to $ALL, the script still starts before the network is brought up via ifconfig. I’ve tried playing with all of the other fields in the ‘init info’ header, to no avail
I’ve checked that the service is activated via chkconfig runlevels 3 and 5 (set to ‘on’) and that the appropriate symlinks are created (S05hostapd-S15hostapd, depending on what I put for ‘required-start’) in /etc/init.d/rc3.d and rc5.d. Going through Yast expert mode, I can see again that the service is activated for the runlevels. Script perms are 755, like all of the other scripts.
As an aside, I was able to add ‘service hostapd start’ as an ifup script in /etc/sysconfig/network/scripts, and it is now started at boot, after the network interface is up. I still need this problem solved for another custom service script, which is also having the same issue.
Any ideas?

### BEGIN INIT INFO
# Provides: hostapd
# Required-Start: $remote_fs
# Should-Start:
# Required-Stop: $remote_fs
# Should-Stop:
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Short-Description: Starts hostapd access point at bootup
# Description: This script will start a secured
# access point on the ath0 interface, bridging
# the wireless network with the ethernet connection.
### END INIT INFO
#
# Any extensions to the keywords given above should be preceeded by
# X-VendorTag- (X-UnitedLinux- X-SuSE- for us) according to LSB.
#
# Notes on Required-Start/Should-Start:
# * There are two different issues that are solved by Required-Start
# and Should-Start
# (a) Hard dependencies: This is used by the runlevel editor to determine
# which services absolutely need to be started to make the start of
# this service make sense. Example: nfsserver should have
# Required-Start: $portmap
# Also, required services are started before the dependent ones.
# The runlevel editor will warn about such missing hard dependencies
# and suggest enabling. During system startup, you may expect an error,
# if the dependency is not fulfilled.
# (b) Specifying the init script ordering, not real (hard) dependencies.
# This is needed by insserv to determine which service should be
# started first (and at a later stage what services can be started
# in parallel). The tag Should-Start: is used for this.
# It tells, that if a service is available, it should be started
# before. If not, never mind.
# * When specifying hard dependencies or ordering requirements, you can
# use names of services (contents of their Provides: section)
# or pseudo names starting with a $. The following ones are available
# according to LSB (1.1):
# $local_fs all local file systems are mounted
# (most services should need this!)
# $remote_fs all remote file systems are mounted
# (note that /usr may be remote, so
# many services should Require this!)
# $syslog system logging facility up
# $network low level networking (eth card, ...)
# $named hostname resolution available
# $netdaemons all network daemons are running
# The $netdaemons pseudo service has been removed in LSB 1.2.
# For now, we still offer it for backward compatibility.
# These are new (LSB 1.2):
# $time the system time has been set correctly
# $portmap SunRPC portmapping service available
# UnitedLinux extensions:
# $ALL indicates that a script should be inserted
# at the end
# * The services specified in the stop tags
# (Required-Stop/Should-Stop)
# specify which services need to be still running when this service
# is shut down. Often the entries there are just copies or a subset
# from the respective start tag.
# * Should-Start/Stop are now part of LSB as of 2.0,
# formerly SUSE/Unitedlinux used X-UnitedLinux-Should-Start/-Stop.
# insserv does support both variants.
# * X-UnitedLinux-Default-Enabled: yes/no is used at installation time
# (%fillup_and_insserv macro in %post of many RPMs) to specify whether
# a startup script should default to be enabled after installation.
# It's not used by insserv.
#
# Note on runlevels:
# 0 - halt/poweroff 6 - reboot
# 1 - single user 2 - multiuser without network exported
# 3 - multiuser w/ network (text mode) 5 - multiuser w/ network and X11 (xdm)
#
# Note on script names:
# http://www.linuxbase.org/spec/refspecs/LSB_1.3.0/gLSB/gLSB/scrptnames.html
# A registry has been set up to manage the init script namespace.
# http://www.lanana.org/
# Please use the names already registered or register one or use a
# vendor prefix.
# Check for missing binaries (stale symlinks should not happen)
# Note: Special treatment of stop for LSB conformance
