1 # DragonFly Release 2.8
4 The DragonFly 2.8 release is here!
6 Wait, no it's not! This is a page set up for work done on the 2.7 development branch, so that we can write it down as it happens. When 2.8 is rolled, we'll use this page for the release.
19 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`.
21 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:
25 We supply a Makefile in /usr to track the pkgsrc tree. We also supply a Git mirror of the NetBSD pkgsrc CVS repo as
26 well as the pkgsrc/wip (work in progress) repo at git://git.dragonflybsd.org/pkgsrc.git. We recommend that
27 users use it, instead of pulling from NetBSD with CVS. Our Git mirror is updated four times a day.
29 ## DragonFly 2.6.x Special Installation and Upgrade Notes
31 **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'.
33 > cd /usr/src/sys/boot
37 **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:
39 > # cd /usr/pksrc/net/bind96;
40 > # bmake all install clean
46 > # cp /usr/pkg/share/examples/rc.d/named9 /etc/rc.d/
47 > # /etc/rc.d/named stop
49 >edit /etc/rc.conf, and remove
56 > named_chrootdir="/etc/namedb"
57 > named_flags="-c named.conf"
58 > named_program="/usr/pkg/sbin/named"
60 > # chown -R named /etc/namedb
61 > # /etc/rc.d/named9 start
63 >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.

82 * kern_udev - A framework to associate optional information with device nodes
83 * initrd (initial ramdisk/malloc disk) support
84 * Removal of shared spinlocks and renaming of the spinlock API
85 * Added support for AES-XTS and AES-CTR to the opencrypto framework
86 * proplib imported from NetBSD

110 * udevd - A support daemon for libdevattr
111 * Kernel programming guide (section 9 man pages) updated and extended.
112 * mkinitrd - A tool to generate an initrd image to be able to boot from crypto, lvm and other devices
113 * crashinfo, a tool to automatically extract some useful information from kernel dumps in a text format
114 * proplib imported from NetBSD
115 * added sha512 support to libmd

125 > ### Contributed Software
126 * Imported drill and libldns as a resolving utility in base as BIND has gone
127 * Imported lvm (Logical Volume Manager)
128 * Imported cryptsetup for use with the new device mapper crypto target, dm_target_crypt
129 * Updated awk to 20100523
