IJack:
Thanks for the concrete reference (pre-3.0 Linux kernels): I missed that in my reading. Both my current U12.04 systems use v_3.2.x Linux kernels. Yet as systemd gathers "strength" it's prudent to expect its demands on Linux kernel/apps interaction to grow .
I consider the extreme case: it grows so far and so fast that original systemd-consistent U_14.04 apps become orphans(?) no longer upgradeable; that is all upgraded apps require a Linux version with deep support for/dependence-on systemd.
In that case I should --- and I'm repeating my weak;y stated original question --- reject U_14.04, stay with U_12.04 and wait for the NEXT U_LTS release which will be systemd-based (and also non-X-Org).

"New kernels" here is a relative phrase. As far as I can see this patch only affects really old kernels - pre 3.0 ones. Do you really use a kernel that old? If so you just continue using an old udev too. I'm guessing that this won't affect many people.
