The info test currently fails (both on sync and tokio), since it uses an outdated sha ("bdbf428cb993bfb50707792cf34f813d31df7355", sould be "f23dc6c07c427c9908f56bdb9829b0a767578ee5" since Sep. 18).
The sha could simply be updated, just the files could be checked , or alternatively another repo that should experience updates even less frequently could be used. Is there a reason julien-c/dummy-unknown is not used? Simultaneous testing of the revision specification?
