Hi, Stefan. Hi, Rob. > My intention is to be able to pass rootfstype= to the kernel and have it > interpreted correctly in the presence of root=, which currently does not > work Stefan, let me repeat: your patch, which does exactly this, got to linux-next: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=21528c69a0d8483f7c6345b1a0bc8d8975e9a172 I think there is some misunderstanding here. First, there is Stefan's patch (based on Rob's patch), which makes the kernel parse rootfstype= even if root= is present. As well as I understand, we all agree that this patch is needed, and it was applied to linux-next, so all is good! Second, there was my suggestion to introduce rdrootfstype= option. You both reacted sceptically, so I withdraw this suggestion -- Askar Safin
