grub cvs ... configfile

grub cvs ... configfile

[Jeff Chua]

I just downloaded the lastest grub2 cvs (1.93) and can't seems to get 
configfile to work... it keeps rebooting.

grub> configfile /grub.cfg
... system reboots

Here's what's in grub.cfg
title Linux Init
         linux /linux/bzc1



Another problem that with the older 1.92 is that it doesn't work with 
initrd with 1.5GB RAM. It works fine with 128MB RAM. Same config, just 
less ram.


Also, it seems grub2 doesn't support very long command line. Anyway to 
increase the command line to more than 255 bytes as in the following ...

title Linux Test
         linux /linux/bzc1 root=/dev/ram0 ro \
         network=fixed \
         netaddr=188.18.88.188 \
         broadcast=188.18.88.191 \
         netmask=255.255.255.192 \
         gateway=188.18.88.139 \
         dns=188.18.88.139 \
         nssdns=0 \
         apm=1 gpm=1 \
         hostname=boston.corp.fedex.com master=hda \
         modules=\"e100\" \
         testing=very_long_line second_line=maybe
         initrd /linux/ramc1.gz



Thanks,
Jeff

The syntax of your configuration file is not correct.  It's a bug that
GRUB reboots in this case.  It's a known bug an it will be fixed and
some documentation for the wiki will be written.

Marco,

Any chance of fixing this ...

Oh sorry, I forgot to reply on this one.  It should all be fixed in
CVS.  Your menu entries should look like this:

@ foo {
  linux ...
  initrd ...
}

@ bar {
  ...
  ...
}

got "parse error" with ...

@ Linux Test {
         linux /linux/bzc1 root=/dev/ram0 ro \
         network=fixed \
         gateway=192.168.243.1 \
         netaddr=192.168.243.118 \

         modules=\"pcnet32\" \
         testing=very_long_line second_line=maybe
         initrd /linux/ramc1.gz
}



Is this the problem or something else ...


Here's my complete grub.cfg ...

I think you have to quote the name:

"Linux Test"

Ok, quoting works, but these two doesn't ...

 	default 2
 	timeout 10


works under grub-1.92.


Thanks,
Jeff.

Yeah, GRUB is still under development.  Things break and features are
missing.  I think in this case I might have broken something. :-)

I'll look at it...soon :)

Hi,

I think the menuentry were much better and more descriptive. I don't
think there is a need to have both and it only confuses people. So I
would propose to remove @-version.

I agree. The "@" is a very odd syntax. Since "menuentry" works as well,
I think "@" should be removed.

It was added because Okuji wanted something short for this.  I do not
care as long as there is a long command.

Marco is right. This was my request. @ is just a command aliased for 
menuentry, and I like it. Since you are not obligated to use @, please do not 
remove it.

Offering multiple commands that do the same thing is not a good design 
philosphy, and from the other comments on this subject I know I'm not 
alone in that belief. No offense, but I don't think one developer 
liking it is a good enough reason.

I still would like to see it removed.

I'm not alone, either. I have talked about this with my collegue in PUPA, and 
he agreed with me.

I'd like to know why it is a bad phylosophy. In many systems, aliases are 
often provided for convenience. Look at test and [. Look at true and :. Short 
cuts are also a kind of aliases. I don't see anything wrong with this. "There 
should be only one way to do a thing" is Python's phylosophy, but Perl 
developers wouldn't agree with you.

Of course, "I like it" is not a good reason. But menuentry is too long to 
type. This is good enough for me.
