The name index '10' has been reserved for GNU/Hurd. Hurd passive translators are stored as a xattr value with name "gnu.translator" [2]. If "gnu.translator" xattr value has been set before calling mkfs.ext2, it will segfault since "gnu." is not present in ea_names[]. $ setfattr -n gnu.translator -v "/hurd/exec\0" ${TARGET_DIR}/servers/exec $ mkfs.ext2 -d ${TARGET_DIR} -o hurd -O ext_attr rootfs.ext2 "1G" Adding "gnu." to ea_names[], allow to create ext2 filesystem for GNU/Hurd with passive translator already set.
