If you must use static addresses and host names, create a Postdeployment script capable of
setting these values.

For SLES images, change the hard links to soft links before capturing the image.
SLES relies on the use of hard links within its file system, and the tar command that captures
the image captures those hard links.
If a partitioning scheme is used during deployment that distributes files to multiple file systems
(like separate /usr and /var partitions), the tar command does not allow hard links to be
established across separate file systems. This generates an error, causing the task to fail.

Follow these guidelines when you capture a Linux OS from a managed system with multiple
disks:
◦
Each disk you want to capture must have at least one partition. Disks mounted with no
partitions are not supported.
◦
You must modify the /etc/fstab file to include the mount points of all partitions on the
disks you want to capture.
Because disks are repartitioned during an image deployment operation, you must ensure
that the contents of the disks you want to capture are listed correctly in the /etc/fstab
file.
For a capture operation to be successful, the dump field for each partition to be captured
must be set to 1. The dump field is the fifth field in the standard mount line. Setting this
field to 1 enables the partition to be captured, and setting this field to 0 (zero) bypasses
the capture.
provides an example of a sample /etc/fstab file. In
, two
additional serial SCSI disks are located on the source system (/dev/cciss/c0d1 and
/dev/cciss/c0d2
), and the system disk resides on /dev/cciss/c0d0.
IMPORTANT:
For the capture operation to be successful,/dev/cciss/c0d1 and
/dev/cciss/c0d2
must be partitioned, and the dump flag must be set to 1.
Example 3 /etc/fstab file entries for a managed system with multiple disks
/dev/cciss/c0d0p1 swap swap defaults 0 0
/dev/cciss/c0d0p2 / reiserfs acl,user_xattr 1 1
Proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
/dev/cciss/c0d1p1 /Disk1 ext3 defaults 1 0
/dev/cciss/c0d2p1 /Disk2 ext3 defaults 1 0
Using the last line in
as a sample, the following table describes each field in
the mount line for device /dev/cciss/c0d2p1.
