You're making perfect sense. We've long known that libdisk(3) needed to be taken out in back of the barn and shot through the head, but there's just been nobody around to do it so we're still stuck with that evil piece of.... code. The person who re-implements libdisk correctly will get a whole box of chocolate chip cookies in the mail from me. :) - Jordan From: The Anarcat <anarcat@anarcat.dyndns.org> Subject: Re: adding Disk::freespace to lib[h]disk Date: Wed, 10 Oct 2001 15:21:25 -0400 > On Wed Oct 10, 2001 at 08:01:22PM +0200, Poul-Henning Kamp wrote: > > > > Just for the record: I'm not actively interested in libdisk... > > Noted. phk removed from cc: :) > > Ok, then I guess libdisk is left to itself now? > > I think libdisk should be rewritten, maybe keeping a compatibility layer > with the current libdisk. > > This is because I think there are some fundamental designs flaws in > libdisk.
