The bug had surfaced before in 8-CURRENT, but got fixed by instead replacing cpio by bsdcpio. See the mailing list discussion on: http://kerneltrap.org/mailarchive/freebsd-current/2008/8/18/2980244/thread This also e.g. surfaces when creating a release CD using release/Makefile, then trying to install from it - the installation routine will bail out on extracting the distributions. >How-To-Repeat: # tar cvf - /var/empty | cpio -i -t tar: Removing leading '/' from member names a var/empty cpio: Malformed number 000555 cpio: Malformed number 00000000166 cpio: Malformed number 11351324133 cpio: Malformed number 000000 cpio: Malformed number 000000 4 blocks (note: the numbers all have a trailing space, causing the "Malformed" output) >Fix: Either: undo the upgrade to cpio 2.8 Or: use bsdcpio in 7-STABLE too Or: change from_ascii() in contrib/cpio/src/copyin.c to accept trailing spaces >Release-Note: >Audit-Trail: >Unformatted:
