One thing that RH's MD/LVM installer doesn't provide is tunability.  With MD the
stripe size is important, and can't be adjusted post-created.  LVM also lets you
set the stripe size in additional to continuity/scatter of block allocation and
the read ahead sector count on the LV level, as well as the extent size on the
VG level (used much less often).  Access to these values in the installer would
be nice.   Otherwise one installs the OS, and then manually creates the data
VG/LVs in order to have finer control.

Hey, you asked what it would take to impress me.
