Archive of KOSmk4 source tree snapshots

KOSmk4 (like all my other projects) began its development long before the first Git commit was made.

As such, it has gone through a lot of changes made over a long period of time. However in the interest of preserving those stages (and especially to provide them to anyone intend on writing their own hobby OS that just happens to stumble over this one), I provide you with this list of snapshots that I've taken before publishing the intial commit with KOS already in a state that I could be proud to present to the world.

In case you're interested in what that state was: When I originally began development, I decided to wait with publishing this fourth revision of the KOS OS series until it had reached a state where it could (once again) present the user with a user-space commandline driven by busybox.

Of course, I could have just dashed towards a goal like that, given the fact that there isn't that much that would be needed to fulfill such a requirement, however I chose to take my time and let KOS grow naturally as I kept on writing.

Note that these snapshots are in no way meant to be usable in any way. They are meant as a guide for how a 10+MiB monolithic kernel such as KOS can take shape over a period of time, and give the keen reader an idea of the pitfalls I made along the way, such that they may not be made by others. Or maybe give them ideas for things I originally planned, but later later chose to abandon.

Also note that these snapshots contain __ice__ folders which are normally excluded from the regular .git (Just to quickly explain: __ice__ folders contain old revisions of files I re-worked, or chose to get rid of, but didn't actually want to delete in case they might be useful at a later point in time. Basically doing what the git does for me now)
