Hello.
I'm using Ubuntu 25.10, and I've detected a possible bug where the test command isn't working properly with ACLs. In Ubuntu 25.04, the command worked correctly.

The command is as follows, it should return 0 but it returns 1.
sudo -u usuariox test -w "/Datos/INFORMES 2026"; echo "$?"

In Ubuntu 25.04, the output was 0, and in Ubuntu 25.10, the output is 1.
User usuariox has write permissions with ACLs.

I have tried the gnutest command as an alternative and it works fine.
sudo -u usuariox gnutest -w "/Datos/INFORMES 2026"; echo "$?"

Please review it.

Thank you very much.
