|
---|
[2648] | 39 | mrmini - Tool to create a boot environment from a distribution
|
---|
[2003] | 40 |
|
---|
| 41 | =head1 DESCRIPTION
|
---|
| 42 |
|
---|
[2648] | 43 | 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.
|
---|
[2003] | 44 |
|
---|
[2648] | 45 | 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
|
---|
[2003] | 46 |
|
---|
[2648] | 47 | The probably more frequent way of calling B<mrmini> is non-interactively from mondoarchive(8) using a dedicated configuration file.

|
---|
| 139 | # mrcachedir points to the directory where the tool will store generated content
|
---|
[2648] | 140 | # If not defined, mrcachedir is under /var/cache/mrmini
