Hi List, I'm happy to report that I've fixed a critical bug in my jail_build(8) utility: - Fixed bug that could cause binary distribution sets to not be unpacked if/when the inodes of the split tar archive pieces did not occur in sequential order. The result would be entire swaths of missing files in the jail destination directory. Problem was missing "-s" argument to force find(1) to produce lexicographically sorted results when building the list of tar pieces to be concatenated into a pipe to tar(1). You can get the updated script here: http://druidbsd.sf.net/download/jail_build.txt or http://druidbsd.sf.net/download/jail_build.gz or http://druidbsd.sf.net/ For those not familiar, my jail_build(8) script can be used to unpack a binary release (found at ftp://ftp-archive.freebsd.org/pub/FreeBSD/releases or ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/old-releases or if you have a CD/DVD-ROM from either Walnut Creek or FreeBSDMall) as a new jail to any desired destination directory. Creating a jail from a binary release is much faster than using the build(7) process. The only downside is that you may not have the absolutely latest code (unless you use the release(7) process to create your binary release from, say, HEAD). NOTE: This may not work for RELENG_9 binary releases as FreeBSD-9 is expected to introduce a new binary release format (shunning the split tarballs of yesteryear for a single tar-xv archive), however this has been tested with every binary release from FreeBSD-1.0 to FreeBSD-8.1 with success. Here's the patch to show what changed: --- jail_build.orig 2011-04-22 14:54:43.000000000 -0700 +++ jail_build 2011-04-22 14:06:56.000000000 -0700 @@ -2,11 +2,11 @@ # -*- tab-width: 4 -*- ;; Emacs # vi: set tabstop=4 :: Vi/ViM # -# Revision: 1.0 -# Last Modified: October 13th, 2010 +# Revision: 1.0.1 +# Last Modified: April 22nd, 2011 ############################################################ COPYRIGHT # -# (c)2010.
