I'm also curious about this.  Please someone correct me if I am wrong,
but I think that the partitions are aligned on 1MB boundaries, so no
need to worry about 4KB erase-block boundaries.

I also read that article, as well as some other related ones, and have
heard hearsay about LVM being "bad" on SSDs, but would appreciate
someone in the know weighing in.  It may also be something to add to
the installation article in the wiki as a sidenote.

Thanks,
