desktop-save-mode blocks startup of spacemacs

[seschwar]

When desktop-save-mode is enabled spacemacs stops after initialization with the prompt Buffer "*emacs*" has a running process; kill it? (y or n). The "running process" is spacemacs checking its repository for updates.

While I can easily answer n and continue when launching Emacs with a frame attached, it's a problem when using emacs --daemon. Due to the question the daemon blocks and doesn't fork. This breaks scripted Emacs startup, both with shell scripts and systemd. The daemon doesn't fork and therefore the script can't continue past emacs --daemon.

This can be easily reproduced by appending the following lines onto the default ~/.spacemacs.

(custom-set-variables
 '(desktop-save-mode t))

Thank you for the report, can you try to delay the first check and see if it allows the process to fork ?

(run-at-time 20 nil
                  (lambda () (spacemacs/check-for-new-version
                              spacemacs-version-check-interval)))
