Invoke `install` separately for each directory to get ownership right --
i.e. not always owned by root. When owned by root, user sessions break
as no user processes are allowed to create directores there. On normal
systems the directories already exist, but in clean environments / NixOS
test VMs, the bug shows.
Before:
$ namei -l /home/user1/.cache/borg
f: /home/user1/.cache/borg
drwxr-xr-x root root /
drwxr-xr-x root root home
drwx------ user1 users user1
drwxr-xr-x root root .cache
drwxr-xr-x user1 users borg
After:
$ namei -l /home/user1/.cache/borg
f: /home/user1/.cache/borg
drwxr-xr-x root root /
drwxr-xr-x root root home
drwx------ user1 users user1
drwxr-xr-x user1 users .cache
drwxr-xr-x user1 users borg
