Concept
To have a utility that will allow for particular behaviour in your bootscripts depending on the choosen boot parameters. So if you would like to choose between different kernels using LILO you can have associated bootscripts which could handle different firewall commands for example for different Linux kernel versions.
Installation procedure
Untar the associated archive, compile & install
tar xvfy cmdinfo20001028.tar.bz2
cd cmdinfo
make all install
This will install cmdinfo in /sbin
Usage
- Make sure your kernel has built-in support for the /proc filesystem and that /proc is mounted.
- Using lilo put in your lilo.conf an entry like append="key=value" or append="key"
- in any location where you like to retrieve a particular value use
cmdinfo key e.g. in a bootscript
export key=`/sbin/cmdinfo key`
- if a key=value was specified, cmdinfo will print on stdout value if called with cmdinfo key, if key was specified without value then 1 will be printed out to stdout, if key was not specified, 0 will be printed.
