Erm no, that's flat out false. You cannot create files in a read-only directory. > * You can modify, read or delete files in a read-only directory. Modify, yes. That isn't changing the directory, so it isn't affected. Read, of course. There's nothing about "read-only directory" that says you shouldn't be able to read the files in it. Delete? Like with creating files, that is flat out false. > * You can mount or unmount volumes in the read-only directory. So? Mounting a volume isn't changing the parent directory. > * You can't list a read-only directory. And that's another falsehood. I don't know where you're getting your information from, but maybe actually TRY IT before you shoot your mouth off. rosuav@sikorsky:~/tmp/readonly$ ls test testdir rosuav@sikorsky:~/tmp/readonly$ chmod -w . rosuav@sikorsky:~/tmp/readonly$ rm test rm: cannot remove 'test': Permission denied rosuav@sikorsky:~/tmp/readonly$ touch othertest touch: cannot touch 'othertest': Permission denied rosuav@sikorsky:~/tmp/readonly$ touch test rosuav@sikorsky:~/tmp/readonly$ sshfs traal: testdir rosuav@sikorsky:~/tmp/readonly$ Or maybe you're lying through your teeth and I should just block you already.
