Seeding the config gets the bar and the keybindings up, and then leaves
you looking at a black screen, because the autostart line that sets the
wallpaper named ~/.local/share/wallpapers/hyprcosmic/current directly.
That is a symlink import-theme --assets maintains, so it does not exist
until a theme has been imported -- which on a machine that has just
installed the package it has not.
The same line waited for the daemon with an unbounded loop:
until awww query >/dev/null 2>&1; do sleep 0.2; done
awww is a Recommends and lives in a COPR, so on a machine that never
enabled that repository nothing ever answered and the loop spun at 5 Hz
for the length of the session.
Both now live in hyprcosmic-wallpaper, which falls back to the
distribution's own images when there is no link yet, gives up on the
daemon after ten seconds, and exits 0 on every path so autostart is never
left supervising a process that cannot finish. Fedora recommends
cosmic-wallpapers so the fallback has something to find; nothing in the
dependency chain pulled it in before.
Verified against all five paths: no awww at all, a daemon that never
answers, a fresh machine with no link, a link pointing at a real file,
and a link left dangling by a deleted theme.

# This was three shell fragments on one autostart line. It became a program for
|
|
# two reasons, both of which cost a first login its desktop:
|
|
#
|
|
# - `current` is a symlink `import-theme --assets` maintains, so it does not
|
|
# exist until a theme has been imported. Naming it directly meant a machine
|
|
# that had just installed the package set no wallpaper at all.
|
|
# - The wait for the daemon was `until awww query; do sleep 0.2; done`, with
|
|
# nothing to stop it. awww is a Recommends and lives in a COPR, so on a
|
|
# machine that never enabled that repository the loop spun at 5 Hz for the
|
|
# length of the session.
|
|
#
|
|
# Both are now bounded and both say so on the session log.
