bup is a program that backs things up. bup has a few advantages
over other backup software:
It uses a rolling checksum algorithm (similar to rsync) to split
large files into chunks. The most useful result of this is you can
backup huge virtual machine (VM) disk images, databases, and XML
files incrementally, even though they're typically all in one huge
file, and not use tons of disk space for multiple versions.
It uses the packfile format from git (the open source version
control system), so you can access the stored data even if you
don't like bup's user interface.
Unlike git, it writes packfiles directly (instead of having a
separate garbage collection / repacking stage) so it's fast even
with gratuitously huge amounts of data. bup's improved index formats
also allow you to track far more filenames than git (millions) and
keep track of far more objects (hundreds or thousands of gigabytes).
Data is "automagically" shared between incremental backups without
having to know which backup is based on which other one - even if
the backups are made from two different computers that don't even
know about each other. You just tell bup to back stuff up, and it
saves only the minimum amount of data needed.
You can back up directly to a remote bup server, without needing
tons of temporary disk space on the computer being backed up. And
if your backup is interrupted halfway through, the next run will
pick up where you left off. And it's easy to set up a bup server:
just install bup on any machine where you have ssh access.
Bup can use "par2" redundancy to recover corrupted backups even if
your disk has undetected bad sectors.
Even when a backup is incremental, you don't have to worry about
restoring the full backup, then each of the incrementals in turn;
an incremental backup acts as if it's a full backup, it just takes
less disk space.
You can mount your bup repository as a FUSE filesystem and access
the content that way, and even export it over Samba.
Upstream changes:
## 2.6.0 / May 3 2011
A rather large release, feature-version bump because of the new
multiple-gateways feature as implemented by Ryan Duryea (way to go!)
Please also note from this release that if you use Git submodules, the
Git-version requirement for the new implementation is now >= 1.5.6, from
previously un-documented. (1.5.6 is new-enough that I think this is
acceptable)
* Upgrade Net::SSH-gateway dependency to 1.1 (fixes a thread-deadlocking bug on
MRI 1.9)
* Respect "dry-run" on transfer methods (Florian Frank)
* Add support for multiple gateways: (Ryan Duryea)
set :gateway, {
'gate1.example.com' => 'server1.example.com',
[ 'gate2.example.com', 'gate3.example.com' ] =>
[ 'server5.example.com', 'server6.example.com' ]
}
* Properly support nested Git submodules, moves Git requirement to >= 1.5.6 [if
you rely upon submodules] (Ken Miller)
* Fetch tags into the remote cache, allows deploying a tag when using Git, with
the remote_cache strategy (Florian Frank)
* Various fixes to path handling bugs in the copt strategy. (Philippe Rathé)
ocsinventory-agent creates inventory data. This agent is the
successor of the former linux_agent which was released with OCS
1.01 and prior. It also replaces the Solaris/AIX/BSD unofficial
agents. The detailed list of supported Operating System is available
in the OCS Inventory Wiki.
Based on PR#44884 by YAMAMOTO Takeshi.
Additionaly, some improvements by me.
Active Management Technology (AMT) tools
descriptions from man pages:
amttool - remotely control Intel AMT managed machines.
amtterm - Intel AMT serial-over-lan (sol) client.
from amt-howto(7):
What is AMT and why I should care?
AMT stands for "Active Management Technology". It provides some remote
management facilities. They are handled by the hardware and firmware,
thus they work independant from the operation system. Means: It works
before Linux bootet up to the point where it activated the network
interface. It works even when your most recent test kernel deadlocked
the machine. Which makes it quite useful for development machines ...
Intel AMT is part of the vPro Platform. Recent intel-chipset based
business machines should have it. My fairly new Intel SDV machine has
it too.
It uses -nostdinc and tries to use #include <stdarg.h> through
a local copy of stdarg.h, which can't work.
Fixed this by putting the relevant builtin stdarg definitions for
NetBSD in the local copy.
NetBSD installation ISO.

memory stick the easy way
I got tired of having to jump through hoops to install NetBSD on my
Eee PC, so I wrote a simple script to take a NetBSD release ISO and
convert it to an image that can be written to a USB memory stick.
To use the script, simply feed it an ISO and tell it where to write
the resulting image:
$ sh mkmemstick.sh i386cd-5.0.1.iso i386memstick-5.0.1.img
The resulting image can be written to a memory stick using dd(1):
$ dd if=i386memstick-5.0.1.img of=/dev/sd0d
Please note that this script depends on the sysutils/cdrtools package
for extracting the contents of the release ISO.
Hopefully this will be integrated with the build process so these
images are available for those who cannot prepare an image due to lack
of access to a NetBSD machine.
New in Version 0.2 (released 2011-04-15):
* Bug fixes:
+ extract-account:
- account extraction left temp files if authorized_keys had
the uchg flag set
- if the user didn't actually exist, a bogus tarball would be
created anyway
+ install-account:
- the home directory was assumed to be /home/${USER}, which
meant that root's files weren't installed properly
- If the user already existed, the order of entries in the
passwd database wasn't preserved. This caused problems with
root accounts because getpwuid(0) started returning the
passwd entry for the 'toor' user (breaking "are you root?"
tests in various scripts).
+ sudo-add:
- if sudo-add couldn't find the sudoers file or couldn't read
it, it didn't remove existing entries when adding or
removing a user (adding duplicate entries if adding a user
that was already there, and silently failing when removing a
user)
- if sudo-add could find and read the sudoers file:
* it would remove the wrong existing entry if the username
of the user being added/removed started with the same
characters as another user higher in the sudoers file
(e.g., adding or removing foo would remove user foobar if
foobar was higher in the sudoers file)
* 'sudo-add -r' would only remove the first instance of a
user from sudoers (a particular problem given the above
bug)
- sudo-add wasn't preserving order if the user was already in
sudoers (order can be significant in sudoers)
* Less verbose output.
Libfind:
- New flag WALK_STRIPLDOT to strip leading "./" like star does
Cdrecord:
- cdrecord now warns about the correct max. CD-Text size
for a single language that is permitted by the standard.
Mkisofs (Maintained/enhanced by Jörg Schilling since 1997, originated by Eric Youngdale):
- Fixed several typos in the mkisofs man page and in mkisofs
Upstream changes:
Bugfixes
* #301: Fixed a bug in local?s behavior when capture=False and output.stdout
(or .stderr) was also False. Thanks to Chris Rose for the catch.
* #310: Update edge case in put where using the mode kwarg alongside
use_sudo=True runs a hidden sudo command. The mode kwarg needs to be octal but
was being interpolated in the sudo call as a string/integer. Thanks to Adam
Ernst for the catch and suggested fix.
* #311: append was supposed to have its partial kwarg's default flipped from
True to False. However, only the documentation was altered. This has been fixed.
Thanks to Adam Ernst for bringing it to our attention.
* #312: Tweak internal I/O related loops to prevent high CPU usage and poor
screen-printing behavior on some systems. Thanks to Kirill Pinchuk for the
initial patch.
* #320: Some users reported problems with dropped input, particularly while
entering sudo passwords. This was fixed via the same change as for #312.
Documentation
* Added a missing entry for env.path in the usage documentation.
