Previously /boot is asumed as the default dir where kernel and initrd is put. However, the directory containing the running kernel image on Atomic systems differs in each installation. Usually something like: /boot/ostree/rhel-atomic-host-b50a015b637c353dc6554c851f8a1212b60d6121a7316715e4a63e2a4113cd72 This means that kdump will not find vmlinuz when installed on an Atomic host, and thus the kdump service will fail to start. In this patch, the kdump boot dir finding behaviour is a little changed. Firstly check whether user has specify a directory explicitly in /etc/sysconfig/kdump. If yes that is respected. Otherwise we assume 1st kernel and kdump kernel are put in the same place under /boot. Then find it according /proc/cmdline and append it to /boot/ Note: So now the KDUMP_BOOTDIR in /etc/sysconfig/kdump is set as empty by default. If user set KDUMP_BOOTDIR to a directory, then he need to take care of all related things himself. otherwise kdump script handle it automatically.
