I'm no speaking about the installer, but an already installed system.

I don't believe there is a solution to the described issue, the blocks
of a newly installed package can make it to the disk and to the fs
metadata, but the information about it written by the package manager to
its database/plain file might not make it to the disk in case of power
failure/panic, so you would end up with an installed package that the
package manager itself doesn't know about! The issue can happen on any
filesystem, not only on UFS.
