rBuilder Online:Raw Filesystem Image
From rPath Wiki
The Raw Filesystem Image creates one or more files representing the entire installed filesystem for the operating system of the software appliance. These files can be copied to a hard disk such as with the "dd" command. These images to not include a boot sector and expect pygrub to be present in order to boot.
One use for this image type is creating a Xen DomU when the filesystem size and structure is maintained at the Xen Dom0 level for consistency.
When building the appliance group to use this image type, the specifications required are those specific to deploying as a Xen DomU (when applicable) and for different architectures (32-bit and 64-bit). The following rMake command is used to build group-example as a Xen DomU and as an installable ISO, each for both 32-bit and 64-bit architectures:
$> rmake build 'group-example[is: x86]' 'group-example[xen, domU is: x86]' 'group-example[is: x86_64]' 'group-example[xen, domU is: x86_64]'
 | If your software appliance requires a boot sector, use the Raw Hard Disk Image. |
The following options can be customized in the Advanced Options section when creating a build of this build type.
- Custom output filename prefix
- Use this to specify a custom prefix for filenames output from the build, overriding the default name-version-architecture prefix.
- Custom Conary installLabelPath setting
- Use this to specify the locations where your software appliance will retrieve software updates, such as a local Conary repository dedicated to the development of your software appliance. (If you do not choose this option, the install label paths are set to locations at rpath.org.)
- Automatically install required dependencies during updates
- Use this if you want the appliance to automatically install additional software on which updates may depend.
- How many MB of free space should be allocated in the image?
- Use this to designate an amount of free space that your software appliance may need in addition to that reserved for the operating system, such as allowance for a growing database.
- How many MB swap space should be reserved in this image?
- Use this to designate a size for the swap file in the filesystem that best meets the needs of your software appliance. The default value for this is 128 MB.
