I guess this related to selinux policy, please help to take a look:

kdump.service 1st time startup will fail with below info
Jun 12 23:28:39 localhost kdumpctl[548]: + ldconfig -r
/var/tmp/initramfs.Lk6NT4
Jun 12 23:28:39 localhost kdumpctl[548]: ldconfig: Can't create
temporary cache file /etc/ld.so.cache~: Permission denied


dracut ran cmd like: 'ldconfig -r /var/tmp/foo' in kdump.service

I'm seeing below selinux audit log:
