From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Stupid 1
Made a 4-disk RAID10, back when 160GB disks were boss and I couldn't afford WD Raptors. Fiddled with some tune2fs options to make it even faster. After a reboot, fsck found some errors. Asked if I want to fix them. I said yes. It asked again for some more errors. I said yes. Eventually I jammed a screwdriver in the keyboard to accept every prompt. After a while of this a grim feeling came over me that fsck might not be doing me a favor. Stopped the machine. Booted into a live CD, mounted the fs, a good number of music and other files were gone. Luckily the corruption wiped mostly larger files like audio and video which were replaceable. I started making backups after that.
Here's what 160GB disks sequential read benchmarks used to look like:

Around the same time I tried to convert Debian to Ubuntu by replacing the Debian repos in apt with Ubuntu's and following with dist-upgrade.
Shouldn't it work though ? Or be close to work with the appropriate options passed down to dpkg
Sadly no. It sounds plausible, which is why I tried it. However there can be unreconcilable package dependencies and all apt can give you is a choice between one broken mess or another.
You might be able to do it if you bypassed apt. Perhaps if you get the list of packages the new OS needs, just download them with apt, then uninstall almost all dpkg packages with purge, then install the new ones.
