- Add `no' keyword, which can be used in the following ways:
no file-system SOMEFS
no makeoptions FOO
no options OPT1[,OPT2[,...]]
no pseudo-device somepseudo
This turns off a previous file-system/makeoptions/options/pseudo-device
entry for the same item.
Grammar support for 'no device DEV at ATTACH' added, but not
implemented yet.
Code changes:
- Convert many simple lists to TAILQs
- Convert prefix to SLIST
- Remove argument names from prototypes.
- Don't bother with custom alloc code for hashtables; just use emalloc()
like everything else.
- Implement ht_remove(), to remove an entry from a hash table.
Add removed entries to a freelist for later reuse.
- Don't selectbase() devices and pseudo-devices at definition time; instead
do it at one pass after the config file has been parsed in fixdevis().
- Rename nvhead to nvfreelist; a more apt name...
- Minor code cleanups.
swap*.c files if they haven't changed from the last time config was
run, so that less stuff will need to be rebuilt (ie, assym.h, upon
which many other things depend) each time config is rerun.
new swap system. The dump specification syntax is now more flexible,
and supports constructs like the following:
config netbsd root on ? type ? dumps on ?
- wildcarded root, fstype, and dump device
config netbsd root on ? type ffs dumps on sd0b
- wildcarded root, ffs root fs, always dump on sd0b
config netbsd root on de0 type nfs dumps on wd0b
- mount an nfs root using de0, and write kernel crash dumps
to wd0b
Also, garbage-collect some now unused code, now that swap configuration
is no longer handled by config(8).
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.
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.
