I'm not sure about that - "man cpio" doesn't give a hint
about flags. On the other hand, tar's -p option does keep
the file mode (permissions), flags and maybe ACLs intact.

I've tried "info cpio" ouch! ouch!, but that's not a
continuous manual that allows easy searching for strings. :-(

Some search in the /usr/src/bin subtree for the "chflags"
call revealed that it is used by the chflags binary, cp,
mv and rm commands, but no hint it is involved directly
in cpio.
