Description of problem:
After each new kernel installation the folder /boot/$(cat /etc/machine-id) is removed and the system unable to start.
Version-Release number of selected component (if applicable):
The component I used here is not the correct one I guess but I did not know which one to choose. This is more or less a general question regarding the boot process on a Fedora system.
When a new kernel is available.
Steps to Reproduce:
Folder /boot/$(cat /etc/machine-id) is removed.
This results in a system which is not bootable anymore and has to be recovered by USB boot.
Folder stays in /boot.
So far I used gummiboot together with the preloader of James Bottomley.
This solutions works for "secure boot" on EFI systems.
As attachment I add a script which I currently use as workaround.

This behaviour started with Fedora 28. I never had this before.
This script is only a workaround because it has to be run after each kernel update. If I forget to run it I have to recover my system by USB stick.
I found the issue. It is this file:
dnf erase grub2-common
Without grub the system does not remove the folder /boot/<machine-id> when installing a new kernel.
On a UEFI system you don't need grub.

Yes, if sd-boot is used then grub2 has to be uninstalled.
Seems like this. But until Fedora 27 it did not behave this way and I cannot remember that I did a grub installation before upgrading. So I think grub was installed all the time.
The problem is that after upgrading from Fedora 27 to 28 your system will not start anymore but you have to boot from USB and repair it.
I have no idea why this change was made but at least I wanted to report it.
This message is a reminder that Fedora 28 is nearing its end of life.
On 2019-May-28 Fedora will stop maintaining and issuing updates for
Fedora 28. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora 'version' of '28'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 28 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
