Hi all
最近mdadm有更新，更新信息里面写道， It is recommended that users remake their initramfs images they boot from after installing this update and then reboot their machine to verify that the new mdadm package does not prevent proper booting of their computer. For safety sake, it's possible to create a totally new initramfs, modify your boot loader configuration to add a test boot instance that uses the new initramfs image as the initrd, and then boot to that test image before updating their known working initramfs images. This update brings mdadm to the latest upstream git repo plus a number of specific bug fixes. It addresses far more issues than the short bug list here depicts. In order to fully test this update, users need to not only install the package, but also rebuild their initramfs images using dracut and then reboot their machine to test that the newly generated initramfs images still work properly on reboot (this obviously only applies to systems that have their root partition on an md handled raid device). This update brings mdadm to the latest upstream git repo plus a number of specific bug fixes. It addresses far more issues than the short bug list here depicts.
我还没有尝试过remake initramfs，不知是否有风险。 另外，mdadm是不是raid相关的软件。我不用raid是不是可以不去更新mdadm， 甚至可以删除相关软件？
