Gentoo/DragonFly

First determine your disk status.

OK. I'll setup DragonFly partition on /dev/ad0

# gpt create ad0
(you may warn or find error here. 
check your disk twice and try "gpt create -f" or "gpt destroy")
# gpt boot ad0
# gpt add ad0
ad0s1 added
# gpt show ad0
(...)

Edit disk label.

# disklabel -B -r -w ad0s0 auto
# disklable -e ad0s0 # vi is invoked, edit like below

# disklabel -r -w ad0s1 auto
# disklabel -e ad0s1 # vi is invoked, edit like below

Use first 1GB(1g) for swap.

device	Filesystem	mount point
/dev/ad0s0a	UFS	/boot
/dev/ad0s1b	HAMMER	/

# newfs /dev/ad0s0a
# newfs_hammer -L ROOT /dev/ad0s1b

UFS for /boot

and HAMMER for / (labeled as "ROOT")

HAMMER is designed for use on storage media greater than 50G. if your disk is less than it, you should use UFS instead (like above).

and don't forget to enable swap :)

# swapon /dev/ad0s1a

Now your partitions are ready. Use "mount" command to mount them.

# mkdir -p /var/mnt/gentoo
# mount_hammer /dev/ad0s1b /var/mnt/gentoo
# mkdir /var/mnt/gentoo/boot
# mount /dev/ad0s0a /var/mnt/gentoo/boot

First check your date/time and update it with "date".

# date 201010211254
(or just specify HHMM)
# date 1254

Go to Gentoo mount point.

# cd /var/mnt/gentoo
# curl -O http://elisp.net/gentoo-dragonfly/files/stage3-x86-20101010.tar.bz2
# tar xvjpf stage3-x86-20101010.tar.bz2

See Installing Portage section of Gentoo Handbook to fetch and unpack official portage tree.

# curl -O http://.../portage-latest.tar.bz2
# cd /var/mnt/gentoo/usr
# tar xvjf ../portage-latest.tar.bz2

As descibed in the Handbook, let's chroot inside Gentoo environment.

# cp -L /etc/resolve.conf /var/mnt/gentoo/etc/
# mount_null /dev /var/mnt/gentoo/dev
# mount_procfs none /var/mnt/gentoo/proc
# chroot /var/mnt/gentoo/ /bin/bash
# env-update
# source /etc/profile

# emerge --sync

Then you need to setup dragonfly overlay.

# wget http://elisp.net/gentoo-dragonfly/files/dragonfly-overlay-20101021.tar.bz2
# mkdir -p /usr/local/portage
# cd /usr/local/portage
# tar xvjf /dragonfly-overlay-20101021.tar.bz2
# chown -R portage:portage /usr/local/portage
# cd /etc
# ln -sf ../usr/local/portage/dragonfly/profiles/default/bsd/dfbsd/x86/2.6 make.profile

and edit "/etc/make.conf" and add "PORTDIR_OVERLAY='/usr/local/portage/dragonfly'". You may need to "emerge -­-metadata" to speed up your emerge.

Check and fix your timezone

See the Handbook for detail

You have only one choice on Gentoo/DragonFly. emerge it :D.

dfbsd-sources need git. so the emerge process would take some minutes.

# emerge dfbsd-sources
# cd /usr/src/sys/config
# config GENERIC
# cd ../compile/GENERIC
# make cleandepend && make depend && make && make install

Setup /etc/fstab to mount filesystems automatically or easily.

Don't forget to add daily cron job "hammer cleanup" if you use HAMMER.

Don't forge to emerge dhcpcd if you use it.
