1. Feature Overview:
Feature Id: 
a. Name of Feature: Reipl support
b. Feature Description
The Linux kernel already has support for a feature called Reipl. We want to enable the installer to
use Reipl. What Reipl does is instruct the 390 where to boot next. This is different than a boot
loader since the 390 does not support a default boot location. Also, this tool can be used by a
system administrator during other times. If they want to shutdown the machine and reboot from a
different partition. There are documentation hits on this as well. Versions of hardware/software:
- LPAR on machine older than z9
- LPAR on z9 or newer (required to reipl from FCP)
- z/VM 5.2 or older
- z/VM 5.4 or later (required to reipl from FCP)
2. Feature Details:
Arch Specificity: Purely Arch Specific Code
Affects Installer: Yes
Delivery Mechanism: Backport
Request Type: Installer - Enhancement from IBM
d. Upstream Acceptance: Accepted
Sponsor Priority 2
f. Severity: Medium
IBM Confidential: no
Code Contribution: IBM code
g. Component Version Target: The reipl code is included in the Linux mainline kernel and the distro
kernels that this feature has been targeted for. The installer does not have an associated upstream
project, so IBM will provide code directly.
3. Business Case
Avoid customer frustration on installation by rebooting automatically instead of manually between
install phase 1 and 2.

Can't really test this as the rawhide build on Z is not working yet.
IBM is signed up to test and provide feedback
Fixed in 'anaconda-12.38.1-1'. 'anaconda-12.38.4-1.el6' included in compose 'RHEL6.0-20091110.0'.
Moving to ON_QA.

Tested with SNAP2 against T on both DASD and SCSI partitions.
I can confirm this is working in z/VM 5.4 for both DASD and FCP LUN.
Tested on tree RHEL6.0-20100603.1 with anaconda-13.21.50-2.el6
