See PXE Setup and NFS Install Server for overall PXE and diskless instructions. This is DflyBSD specific.
That one was hard. dfly/fbsd don’t provide a modified kernel/ramdisk installer. We had to enable NFSv2 for it to point to a diskless and live system.
It was also hard to find out what we need. We choose ISO as it’s easier to mount.
snapshots/x86_64/images/ -- live system images snapshots/x86_64/ -- there's a copy of the before-latest image from above
Note the BOOT
ISO wasn’t enough for the live system (probably it is for the rescue ramdoisk).
Here we go.
mkdir -p /tftpboot/dfly/ cd /tftpboot/dfly/ # RU mirror=https://mirror.macomnet.net/pub/DragonFlyBSD mirror=https://mirror.tochlab.net/pub/DragonFlyBSD
either grab the truly latest
wget $mirror/snapshots/x86_64/images/DragonFly-x86_64-20210427-DEV-v6.1.0.2.g2660f5.iso.bz2
or that copy from the main folder
wget $mirror/snapshots/x86_64/DragonFly-x86_64-LATEST-ISO.iso.bz2
and finally extract it
# tar: Ignoring unknown extended header keyword 'SCHILY.fflags' apt install libarchive-tools bsdtar xjf DragonFly-x86_64-20210427-DEV-v6.1.0.2.g2660f5.iso.bz2
TFTP doesn’t work here as the boot-loader tries to reach /boot
and it wouldn’t consider the root-path
NFS option.
ln -s pxeboot boot/pxeboot.bin ln -s pxeboot_tftp boot/pxeboot_tftp.bin vi /tftpboot/pxelinux.cfg/default label dfly install nfs kernel dfly/boot/pxeboot.bin label dfly install tftp FAILS kernel dfly/boot/pxeboot_tftp.bin vi /etc/dhcp/dhcpd.conf option root-path "192.168.1.20:/tftpboot/dfly";
Now everything works.
1 -- live system then login as `root` 1 -- live system then login as `installer` r -- rescue ramdisk
