Hi Guix!

Today I ran "guix home delete-generations" to remove my old home
generations. It removed generations 0 and 17. I'm on generation 18.

Then I ran "guix gc" and after I noticed I couldn't run a program from
my window manager (its menu is managed from guix home), I tried to look
at what was happening. My config files managed by guix home are now
symlinks that point to non existent store items. Spooky.

Please let me know how I can help diagnose the issue

Actually I figured this out:

Generation 16 used an older guix version where guix home added a . at
the end of file names, so my config looked like this:

(simple-service 'xfce4-terminal home-files-service-type               
  `(("config/xfce4/terminal/terminalrc"
    ,(local-file
      "files/xfce4-terminal/terminalrc"))))

Then, I updated Guix without changing my home configuration, so on
generation 17, guix home created $HOME/config instead of $HOME/.config.
So $HOME/.config/xfce4/terminal/terminalrc (and all other config files)
kept pointing to generation 16's files. After removing the generation
and "guix gc", these files no longer exist, and I'm in trouble :)

So, guix home and guix gc are working as intended, but the change to no
longer adding a "." at the beginning of file names (which makes total
sense) tripped me up.

BTW, there is xdg-configuration-files-service-type, which hides away
those details and helps to migrate seamlessly.  May be helpful for
future readers:
