I remember, that in really old UNIXes creating a dirertory

the mkdir command was something along the lines of:
main( argc, argv )
{
...
chdir(parentdir);
mknod("foo",I_DIR|modes);
link("foo", ".");
link(".","..");
...
}
This was on a version 7, or system V, filesystem.
It is no longer possible to use mknod to make a directory inode. The
rasson for this is that some filesystems can not be made to support the
old semantics, and it is a good idea to have an atomic method to make a
directory.

If you are trying to create directories that users cannot "escape" out of, all you need to do is remove the world rx permissions on the parent directory, and make sure that they don't have access via the group permissions. You might also want to look at chroot.

how mkdir without .. ?
I need in directories without link to parent in it or with link to parent renamed to something exotic name. What is the method to do it without kernel patching in FreeBSD 2.2.X or 3.X ? -- @BABOLO http://links.ru/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
