This adds a safebelt that prevents users to mark more than
one "active" partitions, which will lead to a unbootable
machine, especially in multi-boot configurations.

crontab: errors in crontab file, can't install
Do you want to retry the same edit? yes
[Exit the editor without any changes.]
crontab: no changes made to crontab
[Entry is lost.]
Now crontab will loop until the error is fixed, or the
user answers no.
VT6122 gigabit ethernet chip and integrated 10/100/1000 copper PHY.
The vge driver has been added to GENERIC for i386, pc98 and amd64,
but not to sparc or ia64 since I don't have the ability to test
it there. The vge(4) driver supports VLANs, checksum offload and
jumbo frames.
Also added the lge(4) and nge(4) drivers to GENERIC for i386 and
pc98 since I was in the neighborhood. There's no reason to leave them
out anymore.
remaining consumers to have the count passed as an option. This is
i4b, pc98/wdc, and coda.
Bump configvers.h from 500013 to 600000.
Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device. This broke things like the snd_emu10k1 device, which required
quotes to make it parse right. The no-longer-needed quotes have been
removed from NOTES, GENERIC etc. eg, I've removed the quotes from:
device snd_maestro
device "snd_maestro3"
device snd_mss
I believe everything will still compile and work after this.
concensus seems to be that is best left for doing post-install.

Previously, it would recognize it as a valid shell only
if the basename (nologin) was specified. Now, it will
recognize both the basename and the full path.
NOTE: The full path as adduser(8) understands it is /usr/sbin/nologin.
There is a symlink, /sbin/nologin, but that's deprecated and
only there for backwards compatibility.
relocation is not sufficient for ELF relocatable object format
modules, since accessing the module metadata involves following
pointers between different ELF sections.
This allows kldxref to correctly build linker.hints on the amd64
platform.
to get used to the fact that Perl is no longer part of the base system.
It is practically impossible to install any useful package and not get
Perl automatically pulled in as a dependency. So the typical user will
get their Perl.
This change greatly reduces the amount of manual labor in building the
miniinst.iso in release building.
Centralize the fdctl_wr() function by adding the offset in
the resource to the softc structure.
Bugfix: Read the drive-change signal from the correct place:
same place as the ctl register.
Remove the cdevsw{} related code and implement a GEOM class.
Ditch the state-engine and park a thread on each controller
to service the queue.
Make the interrupt FAST & MPSAFE since it is just a simple
wakeup(9) call.
Rely on a per controller mutex to protect the bioqueues.
Grab GEOMs topology lock when we have to and Giant when
ISADMA needs it. Since all access to the hardware is
isolated in the per controller thread, the rest of the
driver is lock & Giant free.
Create a per-drive queue where requests are parked while
the motor spins up. When the motor is running the requests
are purged to the per controller queue. This allows
requests to other drives to be serviced during spin-up.
Only setup the motor-off timeout when we finish the last
request on the queue and cancel it when a new request
arrives. This fixes the bug in the old code where the motor
turned off while we were still retrying a request.
Make the "drive-change" work reliably. Probe the drive on
first opens. Probe with a recal and a seek to cyl=1 to
reset the drive change line and check again to see if we
have a media.
When we see the media disappear we destroy the geom provider,
create a new one, and flag that autodetection should happen
next time we see a media (unless a specific format is configured).
Add sysctl tunables for a lot of drive related parameters.
If you spend a lot of time waiting for floppies you can
grab the i82078 pdf from Intels web-page and try tuning
these.
Add sysctl debug.fdc.debugflags which will enable various
kinds of debugging printfs.
Add central definitions of our well known floppy formats.
Simplify datastructures for autoselection of format and
call the code at the right times.
Bugfix: Remove at least one piece of code which would have
made 2.88M floppies not work.
Use implied seeks on enhanced controllers.
Use multisector transfers on all controllers. Increase
ISADMA bounce buffers accordingly.
Fall back to single sector when retrying. Reset retry count
on every successful transaction.
Sort functions in a more sensible order and generally tidy
up a fair bit here and there.
Assorted related fixes and adjustments in userland utilities.
WORKAROUNDS:
Do allow r/w opens of r/o media but refuse actual write
operations. This is necessary until the p4::phk_bufwork
branch gets integrated (This problem relates to remounting
not reopening devices, see sys/*/*/${fs}_vfsops.c for details).
Keep PC98's private copy of the old floppy driver compiling
and presumably working (see below).
TODO (planned)
Move probing of drives until after interrupts/timeouts work
(like for ATA/SCSI drives).
TODO (unplanned)
This driver should be made to work on PC98 as well.
Test on YE-DATA PCMCIA floppy drive.
Fix 2.88M media.
This is a MT5 candidate (depends on the bioq_takefirst() addition).
This gets us the info we need on systems which have proprietary tables that
don't match the standard. For instance, an AMI system has a table of type
"OEMB" with an invalid checksum.

callers. These ioctls attempted to enable and disable the ACPI
interpreter at runtime. In practice, it is not possible to boot with
ACPI and then disable it on many systems and trying to do so can cause
crashes, interrupt storms, etc. Binary compatibility with userland is
retained.

Decrease log severity to debug if a protocol is not supported by the
kernel (rpcbind checks /etc/netconfig if a protocol is available).
This avoids "rpcbind: cannot create socket for tcp6" messages
at startup on IPv4-only kernels.
use it, only those with FCode. Add references to dc(4), gem(4) and hme(4)
for obtaining further information about such devices presently supported
by FreeBSD.
- Correct the HISTORY section. There was an eeprom(8) utility in 4.4BSD and
early versions of FreeBSD 2.x.
- Add an AUTHORS section.
