Yes,it does make a difference. I was talking about when the root file system is an NILFS2 partition. When a NILFS2 partition is mounted mount.nilfs2 starts nilfs-cleanerd, if it can't find / in /proc/mounts it won't start, no garbage collection gets done and the partition fills up resulting in an out of memory error. >> The kernel knows where the root is because it was passed it as an >> argument by grub, it's available in /proc/cmdline > > Yes, but the value is not necessarily symlinkable: an NFS mount target > is not, for instance.

I don't need to use an initramfs, one line in the mountfs bootscript is much simpler and works fine. >> Ideally I'd like udev to create the symlink, but I don't know how to >> do that.
