The cpio package contains tools for archiving.
Install cpio by running the following commands:
./configure --prefix=/usr --libexecdir=/tmp/cpio \ --bindir=/bin && make && make install && rm -rf /tmp/cpio
--libexec=/tmp/cpio: This command installs rmt to /tmp/cpio so that it can be removed. The rmt executable is already installed by the tar package in LFS.
--bindir=/bin: This command installs cpio to /bin instead of /usr/bin as per FHS guidelines.
The cpio package contains cpio and mt.
