        Don't try to update crashkernel when bootloader is not installed
    
        Currently when using anaconda to install the OS, the following errors
        occur,
    
            INF packaging: Configuring (running scriptlet for): kernel-core-5.14.0-70.el9.x86_64 ...
            INF dnf.rpm: grep: /boot/grub2/grubenv: No such file or directory
            grep: /boot/grub2/grubenv: No such file or directory
            grep: /boot/grub2/grubenv: No such file or directory
            grep: /boot/grub2/grubenv: No such file or directory
            ...
            INF packaging: Configuring (running scriptlet for): kexec-tools-2.0.23-9.el9.x86_64 ...
            INF dnf.rpm: grep: /boot/grub2/grubenv: No such file or directory
            grep: /boot/grub2/grubenv: No such file or directory
            grep: /boot/grub2/grubenv: No such file or directory
    
        Or for s390, the following errors occur,
    
            INF packaging: Configuring (running scriptlet for): kernel-core-5.14.0-71.el9.s390x ...
            03:37:51,232 INF dnf.rpm: grep: /etc/zipl.conf: No such file or directory
            grep: /etc/zipl.conf: No such file or directory
            grep: /etc/zipl.conf: No such file or directory
    
            INF packaging: Configuring (running scriptlet for): kexec-tools-2.0.23-9_1.el9_0.s390x ...
            INF dnf.rpm: grep: /etc/zipl.conf: No such file or directory
    
        This is because when anaconda installs the packages, bootloader hasn't
        been installed and /boot/grub2/grubenv or /etc/zipl.conf doesn't exist.
        So don't try to update crashkernel when bootloader isn't ready to avoid
        the above errors.
    
        Note this is the second attempt to fix this issue. Previously a file
        /tmp/kexec_tools_package_install was created to avoid running the
        related code thus to avoid the above errors but unfortunately that
        approach has two issues a) somehow osbuild doesn't delete it for RHEL b)
        this file could still exist if users manually remove kexec-tools.
