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`
