Bug#826045: systemd: New kernels are not booted

[Andre Heider]

Just as a reference, maybe it's of some use to others:
I'm using the attached scripts as:
/etc/kernel/postinst.d/zz-systemd-bootd
/etc/kernel/postrm.d/zz-systemd-bootd

They're very basic, but worked for me just fine for the kernel updates 
of the past +2 month.

That's the kind of distribution<->systemd-bootd integration I was 
looking for,

Regards,
Andre
