1 # DragonFly Release 2.8
2 ## x October 2010 (2.8.1)
4 The DragonFly 2.8 release is here!
6 Three release options are now available for 32-bit as well as for 64-bit:
8 * Our bare-bones CD ISO,
9 * a bare-bones bootable USB disk-key image (minimum 1G USB stick needed)
10 * and a GUI bootable USB disk-key image with a full X environment.
14 The release ISO images should be available on most of the [[mirrors|mirrors]]. If the ISO is not available on a certain mirror, please try another one or download it from the DragonFly FTP server.
24 We offer thousands of pre-built [pkgsrc](http://www.pkgsrc.org) packages for this release. The [pkg_radd(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=pkg_radd§ion=ANY) utility may be used to download pre-built binary packages. The path can be overridden by setting BINPKG_SITES in `/etc/settings.conf`.
26 To get a list of all packages, let [pkg_search(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=pkg_search§ion=ANY) download the summary file for that release:
30 We supply a Makefile in /usr to track the pkgsrc tree and we supply a Git mirror of the NetBSD pkgsrc CVS repo at `git://git.dragonflybsd.org/pkgsrcv1.git`. We recommend that
31 users use it, instead of pulling from NetBSD with CVS. Our Git mirror is updated several times a day.
33 ## DragonFly 2.6.x Special Installation and Upgrade Notes
35 **New Loader** - The forth loader is no longer in the system. The new loader, 'dloader', has to be installed before an 'installkernel'. If you are updating from an older system such as DragonFly 2.4 it is recommended to run an installworld before the installkernel to update the loader. Otherwise you can simply do the following before the 'installkernel'.
37 > # cd /usr/src/sys/boot
41 **BIND removal** - BIND is no longer in the base system. If you are using BIND or any of the associated utilities (host, nslookup, etc.), this method will allow you to transition to the version in pkgsrc:
43 > # cd /usr/pksrc/net/bind96;
44 > # bmake all install clean
50 > # cp /usr/pkg/share/examples/rc.d/named9 /etc/rc.d/
51 > # /etc/rc.d/named stop
53 edit /etc/rc.conf, and remove
60 > named_chrootdir="/etc/namedb"
61 > named_flags="-c named.conf"
62 > named_program="/usr/pkg/sbin/named"
64 > # chown -R named /etc/namedb
65 > # /etc/rc.d/named9 start
67 Test your setup with `host`, `dig` and so on. Check for a running `named` process with ps. Error messages should go to `/var/log/messages`.

117 * libdevattr - A library giving access to additional information about kernel device nodes with an API that is mostly compatible with Linux' libudev.
118 * udevd - A support daemon for libdevattr
119 * Kernel programming guide (section 9 man pages) updated and extended.
120 * mkinitrd - A tool to generate an initrd image to be able to boot from crypto, lvm and other devices
