[Linux-cachefs] mount -o remount?

[Daire Byrne <Daire Byrne framestore com>]

David,

Does FS-Cache support mounting an NFS filesystem without "fsc" and then later adding it with a remount? A quick test suggests not. Is there any reason why it couldn't support this? The main reason I ask is that I would like to mount an NFS root filesystem using a simple basic initrd (busybox) but then use fs-cache once I have a more complete Linux distro available (i.e. diskless booting).

On an unrelated note, have you tested cachefiles with ext4? It doesn't seem to work for me (CacheFiles: Lookup failed error -1).
