guix package -u . --dry-run equivalent for guix home

[Remco van 't Veer]

Hi,

Before using guix home, I had a manifest file for all my packages.
Whenever I did a "guix pull", I'd do "guix package -u . --dry-run" to
figure out if anything interesting got updated.  How do I do that when
my manifest is in my home configuration?  Using "--dry-run" on "guix
home reconfigure" only tells me how much will be downloaded.  I tried
tricking "guix package" into telling me with "guix package -p
.guix-home/profile -u . --dry-run" but that gets me an error.

Is it possible to get an package update dry-run like output for guix
home?

Cheers,
Remco
