When testing development kernels I usually rely on the installkernel
script either through the "make install" target of the Kernel source
or manually. This used to work great on Ubuntu on Z.
On Ubuntu 20.04 (freshly installed up to date) this fails however because
/boot/initrd.img is not updated (/boot/vmlinuz is) and thus zipl installs the
wrong kernel/initrd combination rendering the system unbootable.
(with the correct modules already copied to /usr/lib/modules/5.7.0-rc4-06500-gb67ea026badd/)

[Impact]
* initrd link is not updated when using installkernel or "make install" from kernel sources. This leads to boot failure after installing a new kernel with mentioned methods because the kernel does not match initrd.
* It's a regression because for Focal it was working before.
* Issue was reproduced also on Bionic.
* The proposed fixed by Stefan Bader adds a hook in /etc/kernel/postinst.d/ so installkernel will relink the initrd. The kernel DEB packages should not be affected.

[Impact]
* initrd link is not updated when using installkernel or "make install" from kernel sources. This leads to boot failure after installing a new kernel with mentioned methods because the kernel does not match initrd.
* It's a regression because for Focal it was working before.
* Issue was reproduced also on Bionic.
* The proposed fixed by Stefan Bader adds a hook in /etc/kernel/postinst.d/ so installkernel will relink the initrd. The kernel DEB packages should not be affected.
[Test Plan]
* Build a kernel
* sudo installkernel 5.7.0-rc4-06500-gb67ea026badd bzImage System.map /boot
* Check if /boot/initrd or /initrd symlink to the new initrd
[Where problems could occur]
* Installing kernel via: installkernel or "make install", so mostly kernel developer environments
[Other info from developer]
When testing development kernels I usually rely on the installkernel
script either through the "make install" target of the Kernel source
or manually. This used to work great on Ubuntu on Z.
On Ubuntu 20.04 (freshly installed up to date) this fails however because
/boot/initrd.img is not updated (/boot/vmlinuz is) and thus zipl installs the
wrong kernel/initrd combination rendering the system unbootable.
(with the correct modules already copied to /usr/lib/modules/5.7.0-rc4-06500-gb67ea026badd/)
