query runlevels, services and state without using bash. We also provide libeinfo so other programs can easily use our informational functions. As such, we have dropped the requirement of using bash as the init script shell. We now use /bin/sh and have strived to make the scripts as portable as possible. Shells that work are bash and dash. busybox works provided you disable s-s-d. If you have WIPE_TMP set to yes in conf.d/bootmisc you should disable find too. zsh and ksh do not work at this time. Networking support is currently being re-vamped also as it was heavily bash array based. As such, a new config format is available like so config_eth0="1.2.3.4/24 5.6.7.8/16" or like so config_eth0="'1.2.3.4 netmask 255.255.255.0' '5.6.7.8 netmask 255.255.0.0'" We will still support the old bash array format provided that /bin/sh IS a link it bash. ChangeLog for baselayout-1 can be found in our SVN repo.

# QUICK-START
|
|
#
|
|
# The quickest start is if you want to use DHCP.
|
|
# In that case, everything should work out of the box, no configuration
|
|
# necessary, though the startup script will warn you that you haven't
|
|
# specified anything.
|
|
|
|
# WARNING :- some examples have a mixture of IPv4 (ie 192.168.0.1) and IPv6
|
|
# (ie 4321:0:1:2:3:4:567:89ab) internet addresses. They only work if you have
|
|
# the relevant kernel option enabled. So if you don't have an IPv6 enabled
|
|
# kernel then remove the IPv6 address from your config.
|
|
|
|
# If you want to use a static address or use DHCP explicitly, jump
|
|
# down to the section labelled INTERFACE HANDLERS.
|
|
#
|
|
# If you want to do anything more fancy, you should take the time to
|
|
# read through the rest of this file.

# MODULES
|
|
#
|
|
# We now support modular networking scripts which means we can easily
|
|
# add support for new interface types and modules while keeping
|
|
# compatability with existing ones.
|
|
#
|
|
# Modules load by default if the package they need is installed. If
|
|
# you specify a module here that doesn't have it's package installed
|
|
# then you get an error stating which package you need to install.
|
|
# Ideally, you only use the modules setting when you have two or more
|
|
# packages installed that supply the same service.
|
|
#
|
|
# In other words, you probably should DO NOTHING HERE...

#config_eth0="192.168.0.2/24"
|
|
#config_eth0="'192.168.0.2 netmask 255.255.255.0'"

|
# (eth0:1, eth0:2, etc)
|
|
# iproute2 does not do this as there is no need to
|
|
#config_eth0="'192.168.0.2/24' '192.168.0.3/24' '192.168.0.4/24'"

# Or you can use sequence expressions
|
|
#config_eth0="'192.168.0.{2..4}/24'" FIXME - may not work with baselayout2
|
|
# which does the same as above. Be careful though as if you use this and

|
# fallbacks, you have to ensure that both end up with the same number of
|
|
# values otherwise your fallback won't work correctly.
|
|
|
|
# You can also use IPv6 addresses

# Notice that the space has changed to an underscore - do the same with all

|
# variables and not values.
|
|
#
|
|
# Any SSID's in values like essid_eth0="My NET" may need to be escaped

# This means placing the character \ before the character

# So if your SSID is

|
# My \"\\ NET
|
|
# for example
|
