You're right.

Thanks for your replies considering my suggestions :)


Re: suggestion: what about restoring the disklabel from stdin instead of a given file (if not specified) ?

I must admit I didn't think a little on backward compatibility issues.

Creating a temporary file may not be "elegant" to me but if it works (and it
is working fine) leave it as it is. After all that's what really matter. Your
advice is what really counts on the end.

Sorry to choke up this list a bit lately. Besides some issues I encountered
attempting to run it on my hardware I do really want to use this OS daily,
and I am doing my best to learn it. Please, spare me any dumb question but do
not hesitate to state that this or that is a dumb question or go read the
manuals first. I assure you I will never take offense for such replies, they
are part of the learning process.

By the way, I need to say you I have a LOT of respect for your work.

And its sincere :)

Re: may I suggest two new symlinks: newfs_ufs for newfs and newfs_hammer1 for newfs_hammer ?

2020-08-12 Thread Matthew Dillon
For now I'd rather not.  It would certainly be less ambiguous but there is
a lot of history there and, again, potential backwards portability issues.

One thing that would be nice would be for 'newfs' to look at the filesystem
type in the disklabel for the specified device (if possible) and exec the
correct newfs_* program based on that type.  Another big problem, though,
is that the options and other arguments are different for each newfs_*
variant.

Re: can I use the display native resolution on vty0 as on any other vty's using KMS ?

2020-08-12 Thread karu.pruun
Hello

As discussed earlier, the difference between ttyv0 vs others is almost
expected pre-drm. I don't know the syscons code, there might be other
details in play as well and that could be the reason why the algorithm
described earlier does not work out for you. Actually, I tested
another machine with UEFI and a 4K screen, it gives 80x32, which is
not the expected result using the algorithm. So pre-drm, it may work
(eg on my laptop) or it may not work (on the desktop).

However, with drm/radeon/i915 kldloaded, the difference should go
away. That seems unexpected to me.

This said, my laptop shows a difference between cold boot and warm
boot. When I cold boot the laptop and kldload i915, it won't attach or
initialize properly; I'm not sure what is happening. I have to reboot
(with power on), then everything works fine; i915 initializes
properly. Maybe something like this is in play with your machine as
well? You should see the attach etc drm messages in /var/log/messages
if everything is OK.

With UEFI I don't know if there is a utility to change the video mode.
The vidcontrol modes are for VGA, it does not work with UEFI.

The sysctl man says:

---
Some of the variables which cannot be modified during normal system
operation can be initialized via loader(8) tunables.  This can for
example be done by setting them in loader.conf(5).  Please refer to
loader.conf(5) for more information on which tunables are available and
how to set them.

Cheers

Peeter
