Please read the general README file as well.

Interix is a POSIX compatible subsystem for the Windows NT kernel,
providing a Unix-like environment with a tighter kernel integration than
available with Cygwin.  It is part of the Windows Services for Unix
package, available for free for any licensed copy of Windows 2000, XP,
or 2003.  SFU can be downloaded from:

    http://www.microsoft.com/windows/sfu/

Services for Unix 3.5, current as of this writing, has been tested.  3.0
or 3.1 may work, but are not officially supported.  (The main difference
in 3.0/3.1 is lack of pthreads.)

A prebuilt bootstrap kit and prebuilt binary packages for Interix 3.5 are
available from the pkgsrc information page:

    http://www.netbsd.org/Documentation/software/packages.html

=====

At an absolute minimum, the following packages must be installed from
the Windows Services for Unix 3.5 distribution in order to use pkgsrc:

    Utilities -> Base Utilities
    Interix GNU Components -> (all)
    Remote Connectivity
    Interix SDK

When using pkgsrc on Interix, DO NOT install the Utilities subcomponent 
"UNIX Perl".  That is Perl 5.6 without shared module support, installed to 
/usr/local, and will only cause confusion. Instead, install Perl 5.8 from 
pkgsrc (or from a binary package available at the URL above).

The Remote Connectivity subcomponent "Windows Remote Shell Service" does
not need to be installed, but Remote Connectivity itself should be
installed in order to have a working inetd.

Finally, during installation you may be asked whether to enable setuid 
behavior for Interix programs, and whether to make pathnames default to 
case-sensitive.  Setuid should be enabled, and case-sensitivity MUST be 
enabled.  (Without case-sensitivity, a large number of packages including 
perl will not build.)

=====

If SFU is already installed and you wish to alter these settings to work 
with pkgsrc:

* To uninstall UNIX Perl, use Add/Remove Programs, select Microsoft 
  Windows Services for UNIX, then click Change.  In the installer, choose 
  Add or Remove, then uncheck Utilities->UNIX Perl.

* To enable case-sensitivity for the filesystem, run REGEDIT.EXE, and 
  change the following registry key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel

  Set the DWORD value "obcaseinsensitive" to 0; then reboot.

* To enable setuid binaries (optional), run REGEDIT.EXE, and change the 
  following registry key:

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Services for UNIX

  Set the DWORD value "EnableSetuidBinaries" to 1; then reboot.

=====

IMPORTANT NOTES

* The package imanager (either the pkgsrc "su" user, or the user
  running "pkg_add") must be a member of the local Administrators
  group.  Such a user must also be used to run the bootstrap.  This is
  slightly relaxed from the normal pkgsrc requirement of "root".

* The package manager should use a umask of 002.  "make install" will
  automatically complain if this is not the case.  This ensures that
  directories written in /var/db/pkg are Administrators-group writeable. 

* The popular Interix binary packages from http://www.interopsystems.com/
  use an older version of pkgsrc's pkg_* tools.  Ideally, these should
  NOT be used in conjunction with pkgsrc.  If you choose to use them at
  the same time as the pkgsrc packages, ensure that you use the proper
  pkg_* tools for each type of binary package.

=====

KNOWN ISSUES

* It is not necessary, in general, to have a "root" user on the Windows
  system; any member of the local Administrators group will suffice. 
  However, some packages currently assume that the user named "root" is
  the privileged user (these will eventually be fixed).  To accommodate
  these, you may create such a user; make sure it is in the local group
  Administrators.

* "pkg_add" creates directories of mode 0755, not 0775, in $PKG_DBDIR.
  This will be fixed.

  For the time being, install packages as Administrator, or use a
  "chmod -R g+w $PKG_DBDIR" after installing a package to work around it.
