Re: Conditional partitioning/formatting of device possible

You can use a pre script to detect if is previously partitioned or not 
and then use something similar to:

%pre
#!/bin/sh

Discover condition

if condition;
then
     echo "part /boot --fstype ext3 --size=100 --ondisk=$DISCO" >> 
/tmp/part-include
     echo "part pv.100000 --size=1 --grow --ondisk=$DISCO" >>  
/tmp/part-include
     echo "volgroup Merca --pesize=32768 pv.100000" >> /tmp/part-include
     echo "logvol swap --fstype swap --name=Swap --vgname=Merca 
--size=2047" >> /tmp/part-include
     echo "logvol  / --fstype ext4 --name=root --vgname=Merca 
--size=2048" >> /tmp/part-include
     echo "logvol /home --fstype ext4 --size=1000 --name=home 
--vgname=Merca" >> /tmp/part-include
else
     echo "part /boot --fstype ext3 --size=100 --ondisk=$DISCO" >> 
/tmp/part-include
     echo "volgroup Merca --pesize=32768 --useexisting --noformat" >> 
/tmp/part-include
     echo "logvol swap --fstype swap --name=Swap --vgname=Merca 
--size=2047 --useexisting --noformat" >> /tmp/part-include
     echo "logvol  / --fstype ext4 --name=root --vgname=Merca 
--size=2048 --useexisting --noformat" >> /tmp/part-include
     echo "logvol /home --fstype ext4 --size=1000 --name=home 
--vgname=Merca --useexisting --noformat" >> /tmp/part-include
fi

Later in the partitioning section use %include /tmp/part-include

Hope this helps to you :)
