svn commit: r332228 - head/Mk/Uses

[Rene Ladan]

Author: rene
Date: Thu Oct 31 11:34:46 2013
New Revision: 332228
URL: http://svnweb.freebsd.org/changeset/ports/332228

Log:
  Add a new USES for kernel module ports.
  
  USES=kmod takes no arguments and:
  - adds kld to CATEGORIES
  - sets SSP_UNSAFE
  - sets IGNORE if the kernel sources are not found
  - defines KMODDIR to /boot/modules by default, add it to
    PLIST_SUB and MAKE_ENV, and create it upon installation
  - handles cross-referencing kernel modules upon installation and
    deinstallation
  
  Approved by:	bapt

Added:
  head/Mk/Uses/kmod.mk   (contents, props changed)

Added: head/Mk/Uses/kmod.mk
