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. ---------------------- NT configuration ----------------------- Cygnus Win95/NT Configuration Diagnostics Current System Time: Tue Jul 10 20:32:18 2001 WinNT Ver 4.0 build 1381 Service Pack 5 Path: /usr/local/bin /usr/bin /bin /cygdrive/d/ORANT/bin /cygdrive/d/ORA8ISERVER/bin /cygdrive/c/Program Files/Oracle/jre/1.1.7/bin /cygdrive/d/ORADES6I/bin /cygdrive/d/ORANT/ots/bin /cygdrive/d/ORANT/ows/4.0/bin /cygdrive/d/ORANT/orb/ADMIN/CGI /cygdrive/d/ORANT/orb/BIN /cygdrive/c/WINNT/system32 /cygdrive/c/WINNT /cygdrive/d/ORANT/jdk/bin /cygdrive/d/ORA8ISERVER/orb/bin SysDir: C:\WINNT\System32 WinDir: C:\WINNT PWD = `/home/Administrator' USER = `Administrator' MAKE_MODE = `unix' HOME = `/home/Administrator' NUMBER_OF_PROCESSORS = `1' PROMPT = `$P$G' LOGONSERVER = `\\MSD-PC' OS2LIBPATH = `C:\WINNT\system32\os2\dll;' COMSPEC = `C:\WINNT\system32\cmd.exe' !C: = `C:\WINNT\Profiles\Administrator\Desktop' SYSTEMDRIVE = `C:' HOSTNAME = `MSD-PC' PROCESSOR_REVISION = `0502' !D: = `D:\cygwin\bin' PATHEXT = `.COM;.EXE;.BAT;.CMD' COMPUTERNAME = `MSD-PC' CLASSPATH = `D:\ORANT\ots\classes\jts805jdbc.jar;D:\ORANT\ots\classes\oraclejts.jar;D:\ORANT\ows\4.0\classes\wrbjidl.jar;' WINDIR = `C:\WINNT' USERPROFILE = `C:\WINNT\Profiles\Administrator' PS1 = `\[\033]0;\w\007 \033[32m\]\u@\h \[\033[33m\w\033[0m\] $ ' MACHTYPE = `i686-pc-cygwin' PROCESSOR_IDENTIFIER = `x86 Family 6 Model 5 Stepping 2, GenuineIntel' WIN32DMIPATH = `C:\DMI\' OS = `Windows_NT' OLDPWD = `/usr/bin' PROCESSOR_ARCHITECTURE = `x86' TEMP = `/cygdrive/c/TEMP' PROCESSOR_LEVEL = `6' SYSTEMROOT = `C:\WINNT' HOMEDRIVE = `C:' SHLVL = `1' HOMEPATH = `\' USERDOMAIN = `MSD-PC' USERNAME = `administrator' SHELL = `/bin/sh' HOSTTYPE = `i686' OSTYPE = `cygwin' TERM = `cygwin' RDBMS80 = `D:\ORANT' _ = `/usr/bin/cygcheck' TZ = `GMTST0GMTDT-1,M3.5.0/2,M10.5.0/3' HKEY_CURRENT_USER\Software\Cygnus Solutions HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin\mounts v2 (default) = `/cygdrive' cygdrive flags = 0x00000022 HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin\Program Options HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2 HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2\/ (default) = `D:/cygwin' flags = 0x0000000a HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2\/usr/bin (default) = `D:/cygwin/bin' flags = 0x0000000a HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2\/usr/lib (default) = `D:/cygwin/lib' flags = 0x0000000a HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\Program Options a: fd N/A N/A c: hd NTFS 2047Mb 68% CP CS UN PA FC d: hd NTFS 7491Mb 55% CP CS UN PA FC e: cd N/A N/A D:\cygwin\bin /usr/bin system binmode D:\cygwin\lib /usr/lib system binmode D:\cygwin / system binmode c: /cygdrive/c user binmode,noumount d: /cygdrive/d user binmode,noumount Found: D:\cygwin\bin\bash.exe Found: D:\cygwin\bin\cat.exe Found: D:\cygwin\bin\cpp.exe Found: D:\cygwin\bin\find.exe Found: D:\cygwin\bin\gcc.exe Found: D:\cygwin\bin\gdb.exe Found: D:\cygwin\bin\ld.exe Found: D:\cygwin\bin\ls.exe Found: D:\cygwin\bin\make.exe Found: D:\cygwin\bin\sh.exe 56k 2000/12/03 D:\cygwin\bin\cygbz21.0.dll -
