Attached is a patch against partman-auto-raid/5 (released with Etch)
that allows the preseeding of RAID + LVM setup.
It has been tested with the recipe added to the README. The recipe gets
fairly akward though, as "defaultignore{ }", "lvmignore{ }"
and "lvmok{ }" flags need to be set in the correct fashion as both RAID
partitions and LVM partitions overlap in the recipe. All this does not
feel really clean to me but does what it should.
The work was done for a CDD based on Etch and would need forward porting
for the current development version to cope with the changes done in
partman.
