[Voyage-linux] Rebuilding Kernel and Distribution

[Kim-man 'Punky' TSE]

Hi Lee,

It seems kernel-package in squeeze remove the symlink of kernel:

http://packages.debian.org/changelogs/pool/main/k/kernel-package/kernel-package_12.036+nmu1/changelog#versionversion12.001

Moreover, custom kernel seems need a INITRD="YES" environment variable set in order to generate initrd image when 
install a kernel deb.  But I am not sure how to pass this in debian live conf.

So right now I add a new 098-kernel hook script, which reconfigure the kernel that would trigger the generation of 
initrd and symlink.  The symlink hook is resided in config/chroot_local-includes/etc/kernel/postinst.d/

Please try if it works for you.

Regards,
Punky
