NAME

switchconf - Change system configuration to one of many predefined

SYNOPSIS

switchconf [ -f conf_file ] -help | -list | config_scheme

DESCRIPTION

switchconf is a command line tool that helps nomad laptop users to easily change their configuration.

OPTIONS

switchconf takes only one mandatory argument. If this argument is -help, the command synopsis is output. If it is -list, a list of all known configuration schemes is returned for the current set (found in $conf_top_dirs). If the argument is a configuration scheme, this configuration will be installed on the laptop.

switchconf can take an optional argument, which must be first, flagged by -f. This argument specifies the set of configuration schemes to work with. It names a configuration file, with format described below, located on the current directory. If no optional argument is present, the default file /etc/switchconf/conf is used.

CONFIGURATION FILE

The configuration file (default /etc/switchconf/conf) is simple. The following entries are defined:

conf_top_dirs

This specify where are located the configurations schemes.

dest_dir

This specify in which top directory you want to install the new configuration. This option is pretty useful if you want to debug your configuration without overwritting the actual one.

exec_dir_before, exec_dir_after

This specify the name of the exec directory : all files included will be executed before or after configuration changes

run_parts

This specifies the path to the run-parts command which is used to execute the scripts. Leave it empty to use the internal implementation of run-parts.

config_method

This specify the method to use to copy the configuration files, to their places: softlink, hardlink, copy

/etc/switchconf/conf should be written so it is parsable as a shell script - There should be no spaces between the variable name and its value.

SCHEMES

You should create a directory for each configuration scheme you define, including all the files it should set in the system. Inside /etc/switchconf the directories you should create the files including the full path (i.e., /etc/switchconf/home/etc/network/interfaces for /etc/network/interfaces).

No scheme should be named as either the exec_dir_before or the exec_dir_after, unless the conf_top_dirs is moved out of its default directory, /etc/switchconf.

Although it is not really necessary, you should probably ensure that all the files existing in one of the schemes exist on every other scheme, in order to ensure you do not end up in a hybrid state.

FILES

/etc/switchconf/conf

Configuration file.

/var/lib/misc/switchconf.lastcfg

Memory file, has the name of the current active scheme

/var/lock/switchconf

Lock file.

BUGS

Actually no bugs are reported.
