| Install custom ISO image at leaseweb via iPXE boot in console mode. | |
| Here: Installing freebsd-11.0-RC3 | |
| 1. press CTRL-B | |
| If your custom iso is not mounting, and your console is at an iPXE shell, you can: | |
| ``` | |
| dhcp | |
| initrd http://www.dayofdefeat.org/freebsd/mfsbsd-11.0-RELEASE-amd64.iso | |
| ``` | |
| While the iso is downloading, leaseweb iPXE does not include memdisk, so we have to upload it ourselves to another host. | |
| Here's one I found public, though I wouldn't recommend using it: http://preseed.panticz.de/ipxe/memdisk | |
| After the iso is downloaded and we get back a prompt, we can then: | |
| ``` | |
| chain http://preseed.panticz.de/ipxe/memdisk iso | |
| ``` | |
| After boot: | |
| # mkdir /usr/freebsd-dist/ | |
| # cd /usr/freebsd-dist/ | |
| # fetch http://ftp.de.freebsd.org/pub/FreeBSD/releases/amd64/11.0-RELEASE/MANIFEST | |
| # bsdinstall | |
| Nice to know & workarounds: | |
| - you can't load images via HTTPS | |
| - Error code 2a81800 means image to large > out of memory > use a smaller install image |

boot the Alpine Linux iso with reinstall.sh as shown in the README
this gives you Alpine Linux in RAM as a Rescue Environment
I download my isos to /dev/shm - & install qemu & install my custom system (Micro OS)
add a line to /etc/apk/repositories:
http://dl-cdn.alpinelinux.org/alpine/v3.22/community
& install qemu
apk update
apk add qemu qemu-img qemu-system-x86_64
modprobe kvm
cd /dev/shm
wget https://domain.com/my.iso
MYISO=/dev/shm/my.iso
#VNC (kvm)

In Alpine helper scripts are in /sbin/setup-xxxxx (reinstall.sh seems to configure networking - I'm connected over SSH no problem)

reinstall does not seem to support FreeBSD.
