kernel26archck question

Will the archck kernel eventually became the default kernel in current?
What are the benifits of using the kernel26archck?

Please forgive me if this is a dumb question. I have read the threads on
this kernel and understand that it makes it easier for developers and
device loading.

This is why I'm asking...

I just recently updated/upgraded pacman -Syu

         I let it upgrade my kernel to the current 2.6.15.1-3 kernel. After
upgrading I rebooted just to make sure everything was cool. I use Grub
as my bootloader and although I didn't recieve an error I am just faced
with a grub promt. I couldn't boot up arch. Ok no problem, I was
prepared for a situation like this because I dual boot with a back up
arch install. Also, I created multiple boot disks in case one of those get
currupted. I had to use a boot disk to boot into the arch install that
was not upgraded with the new 2.6.15.1-3 kernel.

Initially I thought oh crap! the default kernal changed to the
kernel26archck and my grub/menulst hasn't been updated, but after
checking directories I quickly saw this wasn't the case.  aparently gub
just became currupted during the upgrade. I then reinstalled grub and
everything was fine and I could boot into both arch installs normally. I
upgraded the other install to the 2.6.15.1-3 kernel in current and now I'm
back to normal.

This my my /boot/grub/menu.lst
Even though it works fine, I'm wondering if there is any potential
problems with the way it's set up?

timeout   5
default   0
color light-blue/black light-cyan/blue

title  Arch Linux "hd0-hda"
root   (hd0,0)
kernel /vmlinuz26 root=/dev/hda3 vga=773 ro
initrd (hd0,0)/initrd26.img

title  Arch Linux "hd1-hdb"
root   (hd1,0)
kernel /vmlinuz26 root=/dev/hdb3 vga=773 ro
initrd (hd1,0)/initrd26.img

I'm only guessing that the kernel upgrade caused grub to become
currupted since reinstalling grub to the mbr fixed it.

Thanks in advance for any replys and help.

IMO, never. Arch packages are generally based on vanilla source code from the application developers - the kernel is no different in that respect.

It gives you various enhanced and/or new functionality unavailable in the vanilla kernel, arguably at the expense of some stability - although not in my experience. The archck website has all the details.

I think you may be confusing archck with the recent migration to initrd, which does indeed make kernel package maintenance easier, and uses a different method for boot-time device and file-system loading.

None that I can see, anyway.

Grub might not have been corrupted, but it would be hard to tell now that you've reinstalled it. For future reference, the Grub CLI is very useful in those situations.

Good to hear you're up and running again anyway, regardless of how you got there. smile

Re: kernel26archck question

Thanks for the info tomk, I try to ride a fine line between not messing
with anything that works fine and staying up to date with current stable.
I think I'm going to stay away from archck for now.  I have some really
important custome software from work on my system and it wold totally
set me back weeks if my system fried on me. Thanks again.

Re: kernel26archck question

You're welcome. smile

It occurs to me, though, that stable in Arch is bleeding edge for a lot of other distros, so things can, and do, go wrong - your grub problem, for example, which as you know, had nothing to do with archck. AFAICS, using archck has no effect on the possibility of your "system frying".

Re: kernel26archck question

I was exagerating alittle and yes I realize archck wouldn't fry my system
although I had a bad experience not long ago when my system became
unbootable after a Syu ugrade/update. I don't blame arch for that as
it was my fault for having gone like 6 months before doing a system
upgrade. Yes, I have noticed that arch seems to be a step ahead with the
current stable than many distro's. I've tried many distro's and in my
opinion they don't come close to arch with costomizing, keeping up
with new releases and package managment and keeping bloat down
to a minimum. Because arch can be bold staying close to the so called
bleeding edge, I try to be prepared for the little glitches that no doubt
will pop up from time to time. Hence my back up install and multiple
boot disks. I always keep a updated copy of my /etc on cd aswell. Actually
when I think about it I have had worse luck with things going wrong on
the other distro's I have tried. Maybe thats because I'm smater about
many things since I started using arch over a year ago. I'm slowly
becoming more knoldgable about linux thanks to arch smile
