Follow these instructions to install FreeBSD-14.0 on a dedicated server, from a Linux rescue environment

1. Boot into the rescue console for your dedicated server

SSH into the rescue control as root. Prepare file path or URL of SSH public key.

2. Download and run the installer script

Download and run the mfsBSD-based installer for FreeBSD-14.0, with root-on-ZFS.

wget \
&& chmod +x \
&& ./ [ -d ] [ -r ram ] [ -m (url of own mfsbsd image) ] authorized_keys ...

The wget command may require the parameter "--no-check-certificate" if SSL validation fails on some rescue systems.

Parameters in [ square brackets ] are optional.

You must specify at least one authorized_keys source, both URLs and local files are supported.

Example invocations

./ /tmp/my_public_key

3. Connect via SSH

Wait until the script reports SSH to be available (takes a few minutes) then connect.

ssh -p 1022 mfsbsd@your-host-ip

Once logged in, you can sudo su - to root without a password. You cannot login as root.

If you have trouble with the connection, wait 2 minutes and try again.
