Artyom, do you think we could arrange for Guile-SSH to properly detect
failure to start =E2=80=98guile --listen=E2=80=99 and report it instead of =
retrying?

Perhaps it could check the exit code of =E2=80=98guile --listen=E2=80=99 an=
d distinguish
127 (=E2=80=9Ccommand not found=E2=80=9D) from other exit codes?

(For more context, see <https://bugs.gnu.org/30522>.)

Thanks,
Ludo=E2=80=99.
