be included in object dependencies. config(8) is told to generate
a header for a particular option with the new "defopt" keyword, used
in the files.* system description files. Options that are placed in
header files are not given -D... cpp flags.
This approach allows options to be turned into headers incrementally,
rather than all at once, and allows for non-header options, as well.
and the root device:
- New "file-system" keyword is used to configure file systems into
the kernel.
- New way of specifying root device, which allows root file system
type to always be specified. Examples:
config gennetbsd swap generic
config sdnetbsd root on sd0a swap on sd0b
config nfsnetbsd root on nfs
are replaced by:
config gennetbsd root on ? type ?
config sdnetbsd root on sd0a type ffs swap on sd0b
config nfsnetbsd root on ? type nfs
config lenetbsd root on le0 type nfs
Note that specific network interfaces may now be specified as
the root device.
- swapgeneric.c is no longer used; generate a swap*.c file for each
"config" line in the kernel configuration file.
requires that some ordering requirements are checked by the
back-end C code instead of the parser (dirspecs, maxpart).
* Be more careful to require newline tokens in the grammer where
they are expected, and deal with blank lines, etc. This allows
elimination of a trailing context on newline in the scanner.
* Let the parser set values for "needs-count" and "needs-flag"
instead of making those special cases in the scanner.
* Get rid of '= ' preceeding actions (obsolete yacc syntax)
* Make the scanner not insert an extra newline after includes.
(It was just an accidental side-effect of the ENDFILE stuff.)
on tech-kern. (See man page.) Implementation by Greg Hudson.
Also, remove special case for i386 in vector handling, although this code isn't
actually used any more.
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
