I have been following Fedora Atomic and CoreOS for a while and now I
think I want to shift my server (as opposed to my workstation or laptop
- I have been testing SilverBlue on the laptop) to CoreOS. The server
is basically used for the systems in the Subject - I will eventually
move all the Jekyll and Rails apps (currently running as Docker
containers) to other servers but I want to test out CoreOS on my own
server first before setting up CoreOS VMs - QMail and EZMLM need to be
built from C code and this has been streamlined for me for over a decade
- but now I am thinking of creating a Podman container for Qmail and
Can people comment on any likely difficulties I might have?

I want to install Fedora coreOS on one of my SSD. I would like to use
Btrfs filesystem for Fedora coreOS.
1- Is it possible?
2- If yes, what is the way to do it?
I am working from an existing Linux host (archlinux) on which I
installed "coreos-installer" via cargo.
I have a device Btrfs formated, with a few subvolumes.
Now, the doc says I need to install on an unmounted device. My plan was
to mount subvolumes and then install the OS on the mounted partitions.
Can anyone tells me how to proceed? Maybe use the live ISO installer
instead of coreos-installer? Anyway to chroot the mounted device and
then install Fedora coreos on it (that would be the simplest)?
I plan to move my bare metal server from Fedora 29 atomic to coreOS as I
understood Fedora atomic 29 is ending soon. Even if my server is quite
recent and very basic, I don't want to mess things. I have been looking
for good documentation, but can't hardly find good ones except the
official coreos-installer github README. I take the opportunity of
this move to improve my knowledge of how OSTree works as it is new and I
am far from understanding well all its features.
I have a few basic questions before I go.
1- Is it ok to scp the whole `/sysroot/ostree/deploy/fedora-atomic`
directory as a backup before I go?
2- Is installing coreOS like an upgrade (i.e I will keep my folders like
$HOME and settings in /etc) or will coreOS erase everything?
3- Am I right to think I can use OSTree functionality and install coreOS
in `/sysroot/ostree/deploy/` alongside fedora atomic? This way i could
reverse and boot to fedora atomic in case of issue. If I can do this,
what's the correct way to install coreOS alongside atomic?
Thank you for hints, good pointers and advice.
