After successful installation, the image failed to boot. When I restarted it in single user mode to check, it appears that zfs module is not loaded on startup, and hence the boot failed. I tried to do a modprobe zfs but that failed as the module did not exist for the booting kernel (6.1.11-1).
Is this a known issue? How can I resolve it? Note that when booting single user, I don't have network connectivity, just lo.

Thanks.

Did you select ZFS to install? If not, then the ZFS warning is normal and does not influence the booting (ZFS is on the ISO, warning will go away once the kernel is re-generated on new updates).
For the rest, info/logs are needed, see https://kaosx.us/docs. Installation.log is a must, you can be get by booting from another install, or using the Live session.
