You may have experienced some bug happening on a new kernel but not on 
older ones. But that is not the same as "breaks on every new kernel".

Possibly nitpicking to you, but would you agree to rename this bug as 
"yaird frequently breaks on changed kernel interfaces"?

I fail to see what yaird and this bug has to do with solaris. If you 
mean the operating system by SUN Microsystems, then it cannot even use 
the Linux kernel AFAIK.

No it is not. I suspect you confuse this with bug#457177.

Indeed. And it is not the case for yaird.

It is, however, quite reasonable for an initramfs generator to break on 
changes to kernel interfaces needed to resolve initially mounting the 
root filesystem after boot.

Yaird probes kernel interfaces at build time (rather than using separate 
tools and databases and including probe logic to be executed at boot 
time, like initramfs-tools). This is a design decision, not a bug.
