Re: kernel-image/debian.README; confusion over version numbers


	Ulp.  I am adding the following paragraph to debian.README, it
 will be in the next version of the scripts I upload.  BTW, I'd be
 extremely grateful for any critique on the documentation, which is
 something I need to work on.
First, change the version numbers near the top of debian.rules.  If
you don't, you may overwrite an installed directory, or you kernel may
not be able to find any modules. You have been warned!

  For an explanation on why this editing maybe required, and/or what
  version set it to, consider this. The kernel knows what version it
  is, as given in the kernel Makefile as the variables VERSION,
  PATCHLEVEL, and SUBLEVEL.  It will look for the modules in
  /lib/modules/$VERSION.$PATCHLEVEL.$SUBLEVEL.  The debian scripts
  think they know what the kernel version is, as given in the debian
  file debian.rules as the variable v (near the top). It then proceeds
  to put the modules in /lib/modules/$v.  So, it is essential that the
  kernel (Makefile) and the debian script (debian.rules) agree about
  the version number, or the kernel will never figure out where the
  debian scripts hid the modules. So change the version number in
  debian.rules (v=X.X.XX) to be the same version as given in the
  kernel Makefile (this will be $VERSION.$PATCHLEVEL.$SUBLEVEL).

	Also, the postinst script for the kernel *Offers* to run lilo
 (also offers to make a bootable floppy), but the default is [No], and
 you may choose to ignore these friendly overtures by the
 postinst. (It won't ever just run lilo without explicit permission,
 so one should never have to remove sbin/lilo just to prevent that)

	I apologise for the inconvenience, and thank you for pointing
 out the documentation deficiency.
