Debootstrap 12.04.3 with improvements, not 12.04.0

Asked by bulldozer2003

I would like to debootstrap (or netinstall) 12.04.3 with the new kernel and other improvements. The ISOs are updated or course, but those cannot be used (see bug 77589, link below). The archives that debootstrap or netinstall use are still 12.04.0.

I *could* use the CD if there is a way for me to:
1. skip the partioning step and manually mount the target
2. proceed with the install onto the target
3. skip grub
4. manually enter the chroot and make the necessary changes to make the install bootable

If you'd like details about why I need to do it this way I can provide them, but its inconsequential to the ability to do custom installs with the newer 12.04.3 release sources.

"debootstrap can't chroot" from CD bug:

See the timestamps at that are still from April 2012. I also did a standard netinstall and wound up with kernel 3.2, instead of 3.8 included in 12.04.3, even though /etc/lsb-release claimed it was Ubuntu 12.04.3!

I suppose I could also do some manual work to upgrade a 12.04.0 install to 12.04.3, but I'm not sure what those step are.

Thank you.

For the differences in kernel version for 12.04.0 and 12.04.3 see

The command
sudo apt-get install --install-recommends linux-generic-lts-raring xserver-xorg-lts-raring libgl1-mesa-glx-lts-raring
should upgrade your system to the latest versions (even if installed from the 12.04.0 media)

I spent some time looking at the installer and can see that it essentially does what you've pointed out. In the installer preseed file:
