=head1 EXAMPLES
|
|
|
|
1. Simplest way to export an image. If there is an image in the osimage table named 'foo', then run:
|
|
|
|
B<imgexport foo>
|
|
|
|
foo.tgz will be built in the current working directory. Make sure that you have enough space in the directory that you are in to run imgexport if you have a big image to tar up.
|
|
|
|
2. To include extra files with your image:
|
|
|
|
B<imgexport Default_Stateless_1265981465 foo.tgz -e /install/postscripts/myscript1 -e /tmp/mydir:/usr/mydir>
|
|
|
|
In addition to all the default files, this will export I</install/postscripts/myscript1> and the whole directory I</tmp/dir> into the file called foo.tgz. And when imgimport is called I</install/postscripts/myscript1> will be copied into the same directory and I</tmp/mydir> will be copied to I</usr/mydir>.
|
|
|
|
3. To include postscript with your image:
|
|
|
|
B<imgexport Default_Stateless_1265981465 foo.tgz -p node1 -e /install/postscripts/myscript1>
|
|
|
|
The I<postscripts> and the I<postbootscripts> names specified in the I<postscripts> table for node1 will be exported into the image. The postscript I<myscript1> will also be exported.
