Following are the supported options:

Specifying a <replaceable>mntpoint</replaceable> causes
|
||||||
|
the partition to automatically be mounted.
|
||||||
|
Wic achieves this by adding entries to the filesystem
|
||||||
|
table (fstab) during image generation.
|
||||||
|
In order for wic to generate a valid fstab, you must
|
||||||
|
also provide one of the <filename>--ondrive</filename>,
|
||||||
|
<filename>--ondisk</filename>, or
|
||||||
|
<filename>--use-uuid</filename> partition options as part
|
||||||
|
of the command.
|
||||||
|
Here is an example using "/" as the mountpoint.
|
||||||
|
The command uses "--ondisk" to force the partition onto
|
||||||
|
the <filename>sdb</filename> disk:
|
||||||
|
<literallayout class='monospaced'>
|
||||||
|
part / --source rootfs --ondisk sdb --fstype=ext3 --label platform --align 1024
|
||||||
|
</literallayout>
