What it should do is change based on whether devfs is mounted or not. It doesn't make *any* sense to have /dev/ide/host0/foo/bar in your /proc/partitions entries if you aren't mounting devfs. The /proc/partitions entry is the only way I know of for something like LVM to determine which devices to scan for Volume Groups. If you can't read /proc/partitions, it has to attempt to scan all block devices it recognizes, regardless of whether they are actually on the system or not. This can take several minutes.
