Those lines would definitely switch you to using linux-yocto-rt
and you'd get the latest -rt version that was integrated into the
The only issue is that if there's a kernel recipe in the meta-congatec-x86
you referenced above, you won't use the configuration that was
used for the original build.
In the same manner, you wouldn't get any kernel patches that the
layer was providing.
Unless of course meta-congatec-x86 is using linux-yocto and is
providing configuration fragments or a defconfig. In that case,
you could update them and provide them via a linux-yocto-rt_4.1.bbappend.
