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. |

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 |
