From: Petr Tesarik Subject: Convert sysroot to a bind mount in kdump initrd References: bsc#976864 Upstream: v0.8.17 Git-commit: a532a27d0bb7f69fbf89527fb02e8434fdafa147 In SLES 12 SP2, systemd-fstab-generator no longer ignores non-device root mounts, so it tries to run an actual mount command for root=kdump. This fails, of course, because "kdump" is not mountable. To solve this, pass "rootflags=bind" to the panic kernel, so systemd can create a (bogus) bind mount and be happy. See also kdump-root-parameter.patch.
