Something like: mount -t nfs -o nolock,ro,tcp ${NFS_SERVER}:${NFS_ROOT} /mnt/nfsroot chroot /mnt/nfsroot mount -o fsc,nolock,ro ${NFS_SERVER}:${NFS_ROOT} /mnt/nfsroot mount --move /mnt/nfsroot/mnt/nfsroot /mnt/sysroot umount /mnt/nfsroot mount --move /mnt/sysroot /mnt/nfsroot Slightly convoluted but it works. Starting cachefilesd not long after this seems to be doing what I want too. Thanks, Daire -- Linux-cachefs mailing list Linux-cachefs@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cachefs
