Matthew Flatt pointed out that Racket 8.9 contains a fix for at least one 
problem that could cause a crash at startup, though I wouldn't expect the 
problem to be triggered as long as `/proc/self/exe` is available: 
https://github.com/racket/racket/commit/2f1535ad37f09e23aaf8b640aeebd47a7439a577

You could see if the pending update fixes the problem for you by running: `guix 
time-machine --url=https://git.guix-patches.cbaines.net/git/guix-patches 
--branch=issue-64247 -- shell racket -- racket`
