35 |
|
---|
36 | mrmini - Tool to create a boot environment from a distribution
|
---|
37 |
|
---|
38 | =head1 DESCRIPTION
|
---|
39 |
|
---|
40 | B<mrmini> creates a bootable ISO/USB image using files from the system it runs on. B<mrmini> will try hard to reproduce the environment of its host system including loaded modules to ensure that the system can be booted properly from the created rescue media. B<mrmini> is used by monodarchive(8) to produce the required USB/ISO images but can also be used stand-alone.
|
---|
41 |
|
---|
42 | For stand-alone usage, B<mrmini> may be called without any parameters or switches. It will then interactively ask the user for all information required to create a set of boot/root media. Options on the command line or a configuration file can also be used to alter the way B<mrmini> is working
|
---|
43 |
|
---|
44 | The probably more frequent way of calling B<mrmini> is non-interactively from mondoarchive(8) using a dedicated configuration file.

134 | =head1 CONFIGURATION FILES
|
---|
135 |
|

136 | The system administrator may have a configuration file in F<$HOME/.mondorescue>. The values in this file may overwrite any other configuration file value.
|
---|
137 |
|
---|
138 | Here is an example of such a configuration file:
|
---|
139 |
|
---|
140 | # mrcachedir points to the directory where the tool will store generated content
|
---|
141 | # If not defined, mrcachedir is under /var/cache/mrmini
|
---|
142 | mrcachedir mrmini = /var/cache/mrmini
|
---|
143 |
|
---|
144 | Also look at man mrmini.conf
