my guess is it's not specific to cpio. it's probably a test pulled in via gnulib. in which case it's not really cpio's problem. you could try FEATURES='-sandbox -usersandbox' to see if it builds. otherwise, you should file a bug at bugs.gentoo.org rather than posting to the cpio mailing list. -mike
