l2f.sh script does the following:
- Downloads from Internet and installs OpenZFS packages on the Linux machine
- Finds a space that can be freed and creates a ZFS-pool on the drive
- Downloads and extracts base and kernel FreeBSD distributions
- Creates minimalistic custom FreeBSD configuration, sufficient for subsequent SSH connection
- Installs FreeBSD EFI loader and creates a corresponding UEFI entry
- Reboots the machine into FreeBSD
Warning! Do not try l2f.sh on production and on any system that has any value. This is an early draft of the script. It contains bugs and can make your remote server unusable, destroy your OS, data and ruin entire life.
- Supports UEFI only machines with recent Redhat and Debian distribution families including Centos 8, Debian 11 and Ubuntu 21.10
- l2f.sh can run on console or via SSH. Network connection is required to downloads distribution and package files from internet
- l2f.sh creates a boot EFI partition and a small ZFS filesystem for FreeBSD to start up. The rest of the space, formerly used by Linux, has to be redistributed manually. FreeBSD has to be configured, as well as, additional dist files / packages must be installed manually
On Linux machine run:
wget https://raw.githubusercontent.com/mezantrop/linux2free/master/l2f.sh && sudo bash l2f.sh
- Import SSH keys as suggested by PkHolm
- Migrate some data from Linux filesystems as tux2bsd suggested
- Depenguinator 2.0 and 3.0
- mfsBSD / mfslinux
