Removed suggestion to use root dataset as bootfs #8247
Conversation
The dracut howto proposed to boot from the root dataset of a pool. Apart from this giving problems when booting (as the code seems to expect a child dataset and creates an illegal dataset name when using the root dataset) the technical limitations of the root dataset (among others the inability to rename or destroy through the `zfs` command) resulted in the general consensus to only use it as a container for the datasets in the pool - not as a filesystem itself. Removed the idea to boot from the root dataset. Signed-off-by: Gregor Kopka <[email protected]>

There was a problem hiding this comment.
I'm all for this because of bugs like #1548 (although I wish we could close one that instead)

Removing 6 lines from a non-code file results in not building and decreased coverage... I'm confused. |
The kernel issue is unrelated, the (slightly) decreased coverage is because the testing isn't entirely deterministic. Nothing to see here. |
Motivation and Context
The dracut howto proposed to boot from the root dataset of a pool.
Apart from this giving problems when booting (as the code seems to expect a child dataset and creates an illegal dataset name when using the root dataset) the technical limitations of the root dataset (among others the inability to rename or destroy through the
zfssubcommand) lead to the general consensus that it's best to only use it as a container for the datasets in the pool - not as a filesystem itself.Description
Removed the idea to boot from the root dataset from the dracut howto.
How Has This Been Tested?
