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

# INTERFACE HANDLERS

# For ifconfig support, emerge sys-apps/net-tools

# For iproute2 support, emerge sys-apps/iproute2
|
|
|

# To prefer ifconfig over iproute2
|
|
#modules="ifconfig"
|
|
|
|
# For a static configuration, use something like this

# (They all do exactly the same thing btw)
|
|
#config_eth0="192.168.0.2/24"
|
|
#config_eth0="'192.168.0.2 netmask 255.255.255.0'"

# We can also specify a broadcast

|
|
# If you need more than one address, you can use something like this
|
|
# NOTE: ifconfig creates an aliased device for each extra IPv4 address
|
|
# (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 - does it work?
|
|
# 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
|
|
# (you should always specify a prefix length with IPv6 here)

|
#mtu_eth0="1500"

|
|
# Each module described below can set a default base metric, lower is
|
|
# preferred over higher. This is so we can prefer a wired route over a
|
|
# wireless route automaticaly. You can override this by setting
|
|
#metric_eth0="100"
|
|
# or on a global basis
|
|
#metric="100"
|
|
# The only downside of the global setting is that you have to ensure that
|
|
# there are no conflicting routes yourself. For users with large routing
|
|
# tables you may have to set a global metric as the due to a simple read of
|
|
# the routing table taking over a minute at a time.
