Dongsu Park 8243944c99 sys-kernel: enable metacopy and redirect_dir for overlayfs ... Enable CONFIG_OVERLAY_FS_METACOPY, metadata only copy up feature in overlayfs. When turned on, overlayfs will only copy up metadata when a metadata specific operation like chown/chmod is performed. Full file will be copied up later when file is opened for WRITE operation. More or less like delayed data copy up operation. Enable CONFIG_OVERLAY_FS_REDIRECT_DIR, which is equivalent to "redirect_dir=on" in the kernel command-line. When turned on, overlayfs will copy up directory first, before the actual contents. See also https://github.com/kinvolk/Flatcar/issues/170		2020-11-17 16:25:16 +01:00
