 |
|
Hi! I'm reading up to recompile my kernel, but I'm confused by all the references to bzImage, like
| Code: |
mv /boot/bzImage /boot/bzImage.old
|
| Code: |
kernel /boot/bzImage
|
, or in the sripts I wanted to use:
| Code: |
cp -v /boot/bzImage "/boot/bzImage-$WHEN-$WHAT"
|
I have no bzImage in my boot directory or in the grub.conf file! In its place, I have kernel-2.4.25-gentoo or something similar.
Now, I wonder:
is the name bzImage just some sort of placeholder for "relevant kernel"?
should I replace "bzImage" with the name of my kernel in the scripts and commands I use when reinstalling my kernel?
There IS a bzImage in the /usr/src/arch/i386/boot/something directory. What does IT do? |

hi,
this one saves your _old_ kernel image:

that one is written n your /boot/grub/grub.conf file - it's the ref. to your kernel image:
| Cowboy Feng wrote: |
| Code: |
kernel /boot/bzImage
|
|
the following copies the file /boot/bzImage to /boot/bzImage-$WHEN-$WHAT, where $WHEN and $WHAT are environment variables (they might have been specified in the script, given as parameter to the script, or may be defined elsewhere in your bash env. )

well, that _is_ your kernel. it just was renamed when it has been copied from
| Code: |
/usr/src/linux/arch/i386/boot/bzImage
|
to your boot directory. that allows you to have multiple kernels ready to load, so one can choose (by an appropriate grub.conf - entry) which kernel to boot.
i hope that answered your last question as well

Sorry, I still don't understand.
In the command and script examples above, should I replace bzImage with kernel-2.4.25-gentoo? |

No, bzImage is a file that appears in /usr/linux/..../boot/ after kernel compilation and it should be copyed to your /boot directory with any name you want, no matter kernel-2.4.25-gentoo or kernel-2004 or windows-xp  . |

As long as you make sure your boot program (lilo or grub) refers to your name of choice

You may rename "bzImage" to "vmlinuz" as that is the standard name for kernels in /boot.
But don't ask me why
