Comment 6 for bug 16598

still exist under ubuntu 12.04. - is that expected?

- first of all
/sbin/installkernel: 30: [: /boot unexpected operator

Seems sh version we have on ubuntu (/bin/sh -> dash
) don't allow == during string comparation.

- seems we also don't need call new-kernel-pkg (if someone need package should/could use make-kpkg).
- lack of update-initramfs and update-grub in installkernel script

Seems Ubuntu still using orginal (RedHat) version of /sbin/installkernel script (??).
As I understand this should be Ubuntu specyfic code and someone from Ubuntu team should rewrite/change this.
