Il problema \u00e8 sorto a causa della chiamata nel copyscript della utility cp con le opzioni \u2018-afL\u2019, che venivano elaborate normalmente in GNU Coreutils, ma in Rust Coreutils hanno portato a restituire l'errore \u2018cp: -r not specified; omitting directory \u2019.     <\/p>\n<p>L'errore \u00e8 stato causato da un comportamento diverso nella gestione delle opzioni conflittuali \u2018-L\u2019 e \u2018-a\u2019. L'opzione \u2018-L\u2019 impone di dereferenziare i link simbolici, mentre l'opzione composita \u2018-a\u2019, sostituibile con \u2018-dR \u2014preserve=all\u2019, contiene l'opzione \u2018-d\u2019, che vieta la dereferenzazione dei link simbolici. In Rust Coreutils, l'opzione composita \u2018-a\u2019 veniva scartata completamente invece di rimuovere singolarmente il flag conflittuale \u2018-d\u2019, il che portava alla scomparsa del flag \u2018-R\u2019, necessario per la copia ricorsiva delle directory, e del flag \u2018\u2014preserve=all\u2019, utilizzato per mantenere gli attributi precedenti nella copia.<br \/>\n<br \/>Fonte: <a
