Hi,
I have hit a problem with the 'chroot' system call in cygwin 1.3.2. This
can be seen with the 'chroot' shell utility:
$ chroot /home
chroot: cannot chdir to root directory: No such file or directory
A little more investigation with a simple C program that calls 'chroot'
shows that the system call 'chroot' returns 0 (success) when the path
argument points to a real directory. After the chroot call, getwd returns
the current path with respect to the new root OK. However, chdir and stat
set errno to ENOENT for any path (including "/"), whether the path is with
respect to the old or new root. statfs works OK after the chroot call.
I came across this problem when trying to set up an anonymous ftp server:
this bug forces me to set the home directory for the ftp account to "/":
not exactly the best choice :-)
I have tried this on both NT and W2K: below are the cygcheck outputs for
both.
This problem was pointed out by Symeon Noon on 24 May 2001, but he informs
me that no-one responded to his mail.
Regards,
Peter.
