> package/e2fsprogs: Create y2038 capable file systems by default
* Use inode size of 256 bytes for overlayfs
By default older versions of mkfs.ext4 create file systems with inode
size of 128 bytes. This does not allow for 64-bit timestamps, which
leads to y2038 compatibility warnings. Use 256 bytes inodes.
