MvE  But you are not asking for that.


That is me suggesting that the root partition, as selected by the kernel, should
have a symbolic entry in fstab, partition, not disk unit. And you seem to agree.
But since you are supporting the original suggestion, there must be some kind
of misunderstanding.

RE   It wasn't me doing the asking, but yes, as I understood the proposal,
RE   that is exactly what it was asking  ...


Apparently you were thinking you replied and agreed to the original proposal, but the
part that you were answering to, which is missing here in the quoting, was something else.


I hope this clarifies this and we can stop now.
