I am trying to install stretch on a computer with 2 btrfs disks and EFI.
Is there a howto to do that ? Did someone success ?
I get problems as soon as the partionning in debian installer. What
partitions do I need ? I understand the grub needs them even if btrfs
does not require them. But I am lost, I think due to EFI...
For EFI, you must have one EFI system partition, which must be formatted
as FAT.
So, at least you can't use Btrfs for ESP.
Despite of that, everything can be read/understood by kernel can be your
/boot (mainly for grub) or /.
It will be even simpler if using systemd-boot (previously called
gummiboot), just put kernel (with EFI-stub configured) and initrd into
ESP, mounting ESP as /boot, then everything is done.
For reference, my current fs layout is just like this:
nvme0n1 259:0 0 238.5G 0 disk
├─nvme0n1p1 259:1 0 512M 0 part /boot
└─nvme0n1p2 259:2 0 238G 0 part
├─system-root 254:0 0 32G 0 lvm /
├─system-swap 254:1 0 4G 0 lvm [SWAP]
└─system-home 254:2 0 150G 0 lvm /home
As you can see, I'm using systemd-boot, reusing ESP as /boot.
Then as long as one fs/stacked block device is supported by kernel, you
can use it as you wish.
I see nothing on that in google.
Well, Archlinux has quite nice wiki page for this:
