Colin Watson posted this to the ubuntu-devel mailing list:

Debian has removed reiserfs support from its kernel packages and its
installer (http://bugs.debian.org/717517). I don't really want to keep
maintaining it without Debian; for instance it would mean adding support
for http://bugs.debian.org/696123 as an Ubuntu-specific patch once we
have the underpinnings done. Does anyone feel desperately that we have
to keep this or shall I just go ahead and drop it?

Thanks,

Any thoughts on this?
