Hi all,
I'm trying to use iPXE to boot into a live atomic host. I was able to
successfully create a tree and build the pxelive images using the
build_stage1.sh and build_stage2.sh scripts in the downstream branch of the
sig-atomic-buildscripts github repo.
<https://github.com/CentOS/sig-atomic-buildscripts> When I actually try to
boot a system I receive the following message:
[FAILED] Failed to start switchroot
Looking for more info in the logs I get:
:/# systemctl status initrd-switch-root -l
Failed to switch root: Specified switch root path /sysroot does not seem to
be an OS tree. os-release file is missing.
If it check the /sysroot folder I can see that the squashfs image was
mounted. I can browse into /sysroot/ostree/boot.0/centos-atomic-host/{ID}
and see the entire tree as it is supposed to be.
My iPXE Config is:
#!ipxe
kernel /assets/atomic/new/vmlinuz-3.10.0-693.5.2.el7.x86_64
initrd=initramfs-3.10.0-693.5.2.el7.x86_64.img root=live:
http://matchbox.foo:8080/assets/atomic/new/live-rootfs.squashfs.img
ostree=/ostree/boot.0/centos-atomic-host/81f124c81e835f79bce580ea67f8f8
ba34337b6a244daa5d6b319eb58157fa85/0 debug
initrd /assets/atomic/new/initramfs-3.10.0-693.5.2.el7.x86_64.img
boot
Is there some kind of kernel arg besides ostree= that I am missing that
tells the system to mount the correct os tree? I translated the legacy PXE
file into iPXE since I have an iPXE server but it seems I have all the
parameters.
Thanks for any help you can provide.
