<p class="MsoNormal">Hi<o:p></o:p></p>
<div>
<p class="MsoNormal">I am building Red Hat 5.4 and 5.5 boxes on VMWare and some on HP blades with SAN attached storage. I need to do partition alignment during build which I understand is done automatically in Red Hat 6's version of anaconda and later but not
yet in 5.4, 5.5. So a number of questions:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">* I could not find an option for part in the docs (<a href="http://fedoraproject.org/wiki/Anaconda/Kickstart#part_or_partition">http://fedoraproject.org/wiki/Anaconda/Kickstart#part_or_partition</a>) that easily allow me to set a sector
offset. I have found a number of ways to do this but was wondering if there is an hidden option to do this using part. Currently I am using fdisk to create a partition starting at sector 64 rather than 63 for SAN storage and doing the same for VMWare boxes. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">* How can I easily debug my kickstart? I currently change the kickstart and then reboot the physical server but that is very painful as it has to go through all of the bios checks etc and then sometime I forget to press F12... I tried adding
a sleep 100000 to my pre scripts which works and allows me to run some commands on the command line but I am not sure how to "reparse" the kickstart file to test whether new settings works.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">* Also rather than use clever ways of getting a list of drives or anything similar... is there predefined procedures/variables that I can use, are they available in all scripting languages (bash, python) and where/how could I easily get
a list of available variables for scripting.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">If I need to rtfm, the please point me in the right direction.<o:p></o:p></p>
