Re: [systemd-devel] handling mount failure in initramfs context
Yes, explicit requires/after, all in dependency.

I use 'auto,fail' in fstab line options, however I have rootfs dependency to it so fail means all will fail.

I have a question about mount failure in such case: How can I make sure that upon a mount failure, systemd would stop booting and switch to emergency handling? I will give little more context to the problem at hand. So kdump uses --mount option of dracut to mount file systems in initramfs context. dracut puts right values in /etc/fstab of initramfs which in turn are parsed by systemd and mount units are generated. Now question is what will happen if one of the mount failed? I think currently systemd does not drop us to emergency shell and instead continues to boot. We are trying to figure out how to change this behavior where we can tell systemd to drop into an emergency shell instead. I think Chao used x-initrd.mount option as mount option and that changes the behavior. With this option the mount unit becomes required by initrd-root-fs.target rather than it used to be local-fs.target. And the way these targets are configured, we drop into emergency shell with other untis isolated. Point being that usage of x-initrd.mount to achieve the desired behavior sounded hackish to me. Nowhere systemd guarantees that usage of this option will ensure certain dependencies. I think this option just means that file system will be mounted in initramfs. So is there a better way to achieve what we are looking for.
