Better just leave permissions to the system. > After that, permissions work as expected inside "myfolder" and new > subfolders. Even on H:. But I'm not sure to understand why. I would have > expected that a simple chmod on myfolder would have be enough, instead of > the obscure setfacl. setfacl is far from obscure. chmod was never a useful tool for complicated permissions control. But to the both of them you better not use either outside the Cygwin root directory. Change the cygdrive entry in your /etc/fstab to contain noacl option and your life suddenly become easier. >> none /cygdrive cygdrive noacl,binary,nouser,posix=0 0 0 > Anyway, in my initial report, the "getfacl: b: Invalid argument" message > looks really abnormal. It looks strange, that's right. May be icacls would shine some light. But given this is not a Cygwin root, it's better to not enforce Cygwin permissions on it. -- With best regards, Andrey Repin Wednesday, January 24, 2024 17:25:40 Sorry for my terrible english... ^ permalink raw reply [flat|nested] 4+ messages in thread
