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.

of rc-scripts. Everything here might as well have been spoken by

|
- User Variables -
|
|
Variables must always be enclosed by {}
|
|
e.g. ${foo} ${bar}
|
|
- Internal Shell Variables -
|
|
Do not use {} with internal variables unless appropriate
|
|
e.g. case $1 in
|
|
e.g. foo=$IFS
|
|
e.g. echo "blah${1}123"
|
|
- Assigning with Quotes -
|
|
When assigning to a variable from another variable, you should
|
|
not need quotes. However, you do when assigning from a subshell.
|
|
e.g. foo=${bar}
|
|
e.g. foo="$(uname -a)"

|
- Brackets -
|
|
Always use the [ ... ] form instead of [[ ... ]] as the later only really
|
|
works in bash, and we should support as many shells as we can.
|
|
- Quoting -
|
|
When dealing with strings, you should quote both sides.

- Structure -

Use the more compact form

e.g. while ... ; do
|

Do not use the older form
|
|
e.g. if ...
|

then
|
|
- Functions -
|
|
Use the more compact form
|

Do not lead with 'function '

e.g. function foo() {
