Oh, wow! Yes!
Let's make a change that's really dmraid upstream's business in Debian
only. Let's do it at this stage of the release cycle, *and* let's do it
without giving *any* thought to issues it might cause for existing dmraid
users who upgrade from Etch to Lenny.
Not to mention that this would require also updating partman-dmraid,
grub-installer and maybe hw-detect.
Sounds like an excellent plan Otavio, really.
The fact is that parted changed, and apparently did so without any
coordination with dmraid developers (and I also wonder about other
devicemapper usages).
Even if it's theoretically an improvement, such uncoordinated changes are
called "regressions" as they tend to break existing software/systems.
