Hello Scott,

I'm not sure whether you are still confused about why we need Azure specific code, or is there anything I can do to help make any progress on this merge?

Thanks

The reason is FreeBSD on Azure have more than 1 disks attached, and the rootfs located in one disk, for example, /dev/da0, but I cannot directly write something below:
/dev/da0 / ufs rw 1 1
Because the rootfs may be switched to /dev/da1. The solution is label the disk. For FreeBSD on Azure, I labeled /dev/da0 with "rootfs", so for get_mount_info, I have to find "rootfs" first, and then find the corresponding /dev/da0.

But on Linux, there is a /proc/$$/mountinfo to help find the device. For Azure, there is also /dev/disk/cloud/azure_root on Linux.
Both make the get_mount_info easy to implement.

The only thing I had left was that I'm still confused as what why we need azure specific code in that code path.

I have to think about it some more and probably go play with it a little on freebsd.
