trying to use the ipfilter suite with PicoBSD poses problems. Ipfstat
uses /kernel and /dev/kmem to read the filter statistics and this seems
not available on PicoBSD. Sure this is because the PicoBSD kernel is
without any symbols and is gzipped, and is not even in the root file
system. There are all good reasons why this is so (even if PicoBSD is
used from a flash ROM instead of a floppy.) But could one not make
kernel and kmem available anyway using the kernfs virtual file system?
I could imagine that we need not absolutely strip the kernel from its
symbol table. We could still gzip the kernel. Given that the kernel
is loaded into physical memory, could it not be accessible from there
to the kernfs virtual file system? Or mapped into the mfs root file
system? How hard would it be?
There are a number of system tools that use kernel and kmem, moving
all of them to something like sps and vm etc. would be a lot of
repetitive work, there should be a more fundamental solution...
