[coLinux-users] making sparse files for partitions...

(Sent this to -devel while it probably should have been sent to -users)


> I recently discovered I was running out of space on my main partition and needed to allcoate a new file to host a subset of it (/usr portage in this case). I checked the wiki, and it suggests using fsutil (available on xp only, though ntfs supports spare files on any windows version afaik) or making a non-sparse file using dd.
