I think we’d rather fix the permissions of those files than document the
bug.

On my laptop permissions seem to be good:

--8<---------------cut here---------------start------------->8---
$ ls -ld ~/.ssh/authorized_keys 
lrwxrwxrwx 1 ludo users 59 Dec 10 23:36 /home/ludo/.ssh/authorized_keys -> /gnu/store/k79g5iaaa7gij52nrbhjz6fqq7banzdz-authorized_keys
$ ls -ld ~/.ssh 
drwx------ 3 ludo users 4096 Dec 10 23:36 /home/ludo/.ssh/
$ ssh localhost uname
Linux
--8<---------------cut here---------------end--------------->8---

Maybe there are cases when this is not the case, maybe when ~/.ssh does
not exist prior to running ‘guix home reconfigure’?

Thanks,
Ludo’.
