|

* lib/lsb/init-functions: Merged the contents of etc/init.d/lfs-functions and
|
||||
standardized comment headers.
|
||||
* etc/init.d/lfs-functions: Removed.
|
||||
* etc/default/rc, etc/default/rc.site: moved majority of etc/default/rc.site
|
||||
into etc/default/rc as the configuration items are not generally user
|
||||
configurable items.
|
||||
* etc/init.d/udev: Changed trigger commands to use both subsystem and device
|
||||
types, per udev documentation.
|
||||
|
||||
2011-05-18 DJ Lucas <dj@linuxfromscratch.org>
|
||||
* /sbin/ifup, /sbin/ifdown: Complete rewrite for use as standalone tools
|
||||
* etc/init.d/network: Rewrote script to account for new ifup and ifdown
|
||||
* sbin/ifup, sbin/ifdown: Complete rewrite for use as standalone tools.
|

* etc/init.d/network: Rewrote script to account for new ifup and ifdown.
