Okay, I see there has been some discussion on this earlier, based on a proposal by Ram Pai, so it pretty much comes down to redesigning this right. I see some issues with his proposal (device numbers exported to userspace in text form should be separated into major:minor form, for one thing.) I know the util-linux-ng people have also had issues with /proc/mounts that they would like resolved in order to finally nuke /etc/mtab.
Is Ram still working on this? I'd like to help make this happen so we can be done with it.
