warning: Failed to remount /boot read-only: Device or resource busy

[clime]

During deploy operations that require bootconfig swap: yes;, I am getting the warning:

warning: Failed to remount /boot read-only: Device or resource busy

I think it is because, boot is not being remounted with MS_BIND flag there. I have /boot on the root partition so I think it is trying to mount the whole root partition ro when the MS_BIND flag is missing (please, confirm, i am not completely sure about this).

But I believe if you add MS_BIND flag here https://github.com/ostreedev/ostree/blob/master/src/libostree/ostree-sysroot-deploy.c#L2461, it will solve the problem.
