  • fix typo in label-partitions-as-necessary which doesn't seem to work
  • Update to busybox 1.7.2
  • perl is now required at restore time to support uuid swap partitions (and will be used for many other thigs

in the future for sure)

  • next mindi version will be 2.0.0 due to all the changes made in it (udev may break working distros)
  • small optimization in mindi on keyboard handling (one single find instead of multiple)
  • better interaction for USB device when launching mindi manually
  • attempt to automatically guess block disk size for ramdisk
  • fix typos in bkphw
  • Fix the remaining problem with UUID support for swap partitions
  • Updates mondoarchive man page for USB support

  • Tries to add udev support also for rhel4
  • Fix UUID support which was still broken.
  • Be conservative in test for the start-nfs script
  • Update config file for mindi-busybox for 1.7.2 migration
  • Try to run around a busybox bug (1.2.2 pb on inexistant links)
  • Add build content for mindi-busybox in pb
  • Remove distributions content for mindi-busybox
  • Fix a warning on inexistant raidtab
  • Solve problem on tmpfs in restore init (Problem of inexistant symlink and busybox)
  • Create MONDO_CACHE and use it everywhere + creation at start
  • Really never try to eject a USB device
  • Fix a issue with &> usage (replaced with 1> and 2>)
  • Adds magic file to depllist in order to have file working + ldd which helps for debugging issues
  • tty modes correct to avoid sh error messages
  • Use ext3 normally and not ext2 instead
  • USB device should be corrected after reading (take 1st part)
  • Adds a mount_USB_here function derived from mount_CDROM_here
  • usb detection place before /dev detection in device name at restore time
  • Fix when restoring from USB: media is asked in interactive mode
  • Adds USB support for mondorestore
  • mount_cdrom => mount_media
  • elilo.efi is now searched throughout /boot/efi and not in a fixed place as there is no standard
  • untar-and-softlink => untar (+ interface change)
  • suppress useless softlinks creation/removal in boot process
  • avoids udevd messages on groups
  • Increase # of disks to 99 as in mindi at restore time (should be a conf file parameter)
  • skip existing big file creation
  • seems to work correctly for USB mindi boot
  • Adds group and tty link to udev conf
  • Always load usb-torage (even 2.6) to initiate USB bus discovery

  • udevd remove from deplist s handled in mindi directly
  • better default for mindi when using --usb
  • Handles dynamically linked busybox (in case we want to use it soon ;-)
  • Adds fixed devices to create for udev
  • ide-generic should not be part of the initrd when using libata v2
  • support a dynamically linked udev (case on Ubuntu 7.10 and Mandriva 2008.0 so should be quite generic) This will give incitation to move to dyn. linked binaries in the initrd which will help for other tasks (ia6 4)
  • Improvement in udev support (do not use cl options not available in busybox)
  • Udev in mindi
    • auto creation of the right links at boot time with udev-links.conf(from Mandriva 2008.0)
    • rework startup of udev as current makes kernel crash (from Mandriva 2008.0)
    • add support for 64 bits udev

  • Add USB Key button to Menu UI (CD streamer removed)
  • Attempt to fix error messages on tmp/scratch files at the end by removing those dir at the latest possible.

4<h3>BusyBox is licensed under the GNU General Public License, version 2</h3>
6<p>BusyBox is licensed under <a href="">the
7GNU General Public License</a> version 2, which is often abbreviated as GPLv2.
8(This is the same license the Linux kernel is under, so you may be somewhat
9familiar with it by now.)</p>
11<p>A complete copy of the license text is included in the file LICENSE in
12the BusyBox source code.</p>
14<p><a href="/products.html">Anyone thinking of shipping BusyBox as part of a
15product</a> should be familiar with the licensing terms under which they are
16allowed to use and distribute BusyBox.  Read the full test of the GPL (either
17through the above link, or in the file LICENSE in the busybox tarball), and
18also read the <a href="">Frequently
19Asked Questions about the GPL</a>.</p>
21<p>Basically, if you distribute GPL software the license requires that you also
22distribute the source code to that GPL-licensed software.  So if you distribute
23BusyBox without making the source code to the version you distribute available,
24you violate the license terms, and thus infringe on the copyrights of BusyBox.
25(This requirement applies whether or not you modified BusyBox; either way the
26license terms still apply to you.)  Read the license text for the details.</p>
28<h3>A note on GPL versions</h3>
30<p>Version 2 of the GPL is the only version of the GPL which current versions
31of BusyBox may be distributed under.  New code added to the tree is licensed
32GPL version 2, and the project's license is GPL version 2.</p>
34<p>Older versions of BusyBox (versions 1.2.2 and earlier, up through about svn
3516112) included variants of the recommended "GPL version 2 or (at your option)
36later versions" boilerplate permission grant.  Ancient versions of BusyBox
37(before svn 49) did not specify any version at all, and section 9 of GPLv2
38(the most recent version at the time) says those old versions may be
39redistributed under any version of GPL (including the obsolete V1).  This was
40conceptually similar to a dual license, except that the different licenses were
41different versions of the GPL.</p>
43<p>However, BusyBox has apparently always contained chunks of code that were
44licensed under GPL version 2 only.  Examples include applets written by Linus
45Torvalds (util-linux/mkfs_minix.c and util_linux/mkswap.c) which stated they
46"may be redistributed as per the Linux copyright" (which Linus clarified in the
472.4.0-pre8 release announcement in 2000 was GPLv2 only), and Linux kernel code
48copied into libbb/loop.c (after Linus's announcement).  There are probably
49more, because all we used to check was that the code was GPL, not which
50version.  (Before the GPLv3 draft proceedings in 2006, it was a purely
51theoretical issue that didn't come up much.)</p>
53<p>To summarize: every version of BusyBox may be distributed under the terms of
54GPL version 2.  New versions (after 1.2.2) may <b>only</b> be distributed under
55GPLv2, not under other versions of the GPL.  Older versions of BusyBox might
56(or might not) be distributable under other versions of the GPL.  If you
57want to use a GPL version other than 2, you should start with one of the old
58versions such as release 1.2.2 or SVN 16112, and do your own homework to
59identify and remove any code that can't be licensed under the GPL version you
60want to use.  New development is all GPLv2.</p>
62<h3>License enforcement</h3>
64<p>BusyBox's copyrights are enforced by the <a
65href="">Software Freedom Law Center</a>
66(you can contact them at, which
67"accepts primary responsibility for enforcement of US copyrights on the
68software... and coordinates international copyright enforcement efforts for
69such works as necessary."  If you distribute BusyBox in a way that doesn't
70comply with the terms of the license BusyBox is distributed under, expect to
71hear from these guys.  Their entire reason for existing is to do pro-bono
72legal work for free/open source software projects.  (We used to list people who
73violate the BusyBox license in <a href="/shame.html">The Hall of Shame</a>,
74but these days we find it much more effective to hand them over to the
77<p>Our enforcement efforts are aimed at bringing people into compliance with
78the BusyBox license.  Open source software is under a different license from
79proprietary software, but if you violate that license you're still a software
80pirate and the law gives the vendor (us) some big sticks to play with.  We
81don't want monetary awards, injunctions, or to generate bad PR for a company,
82unless that's the only way to get somebody that repeatedly ignores us to comply
83with the license on our code.</p>
85<h3>A Good Example</h3>
87<p>These days, <a href="">Linksys</a> is
88doing a good job at complying with the GPL, they get to be an
89example of how to do things right.  Please take a moment and
90check out what they do with
91<a href="">
92distributing the firmware for their WRT54G Router.</a>
93Following their example would be a fine way to ensure that you
94have also fulfilled your licensing obligations.</p>
