Issue: 

  A Linux Stage 2 Sync fails with 


               RSP_SYNC_ERROR SYNC_ERROR_DEPLOY_MICROKERNEL STATUS_ERROR

               Details: Failed to deploy microkernel to <host>: initramfs staging failed: 0 2


Solution:

    The source server needs to have at least 20 MB free in /var/tmp.   If it does not, then when the target is replicated from the source, there is not enough free space in /var/tmp of the target to deploy the RackWare microkernel.  
Check the amount of free space in the source file system containing /var/tmp. If there is less than 20 MB free, remove some files from it so that there will be 20 MB free.
