Hello,

Is there a way to get initrd.img and vmlinuz symlinks in /boot or / that
are automatically updated to point to the newest installed kernel?


Thanks,

-Nikolaus

Huh? I don't have any links in /boot.... Not on any of 3 different
systems here at home. If you are creating them yourself, you'll have to
manage them yourself.

Debian and IIRC OpenSUSE can manage these links automatically. They're
very convenient if you are unable to regenerate the boot loader
configuration after every kernel update (e.g. because you manage the
boot loader in another OS). You just configure the /vmlinuz and
/initrd.img locations and are done with it permanently.

Best,

I am not sure what you are asking, but when yum updates a kernel the
system will automatically boot from the latest kernel installed.

Here's the script I'd run manually every time I upgraded my kernel:

#!/bin/bash

cd /

mv vmlinuz vmlinuz.old
mv initrd initrd.old

NEW_KERNEL=`rpm -q kernel | tail -1 | sed -e 's/kernel-//'`
ln -s boot/vmlinuz-$NEW_KERNEL vmlinuz
ln -s boot/initramfs-$NEW_KERNEL.img initrd

exit 0
