Hi,
I think its easier to download a new tinycore image and burn it to CD than to leave it open and try to add a new core if a newer version comes out. Maybe you complain the unused CD space, but thats the price of reliability, even if you have to manage it for a school classroom.
If your frugal installation(s) won't work well with the new CD (this happened with tc-4.1 to 4.2 afair) you will be happy to have the older CD to save your data and note what extensions you were using before you prepare a new frugal installation with the newest versions of your extensions too.
Also with tc 4.6.1 to 4.6.2 i found a problem: noscript on firefox failed to actualize.
So I ran Apps to actualize firefox and deps and found that openssl-0.9.8.tcz also failed.
Browsing the extensions I found openssl-1.0.0.tcz and downloaded it.
Now it was possible to run firefox and actualize noscript too.
As openssl.0.9.8.tcz probably has security holes I wanted to throw it out. Apps listed about 10 dependencies and told me that it cannot be removed. So I left it where it is.
Now I create a new frugal installation with actual extensions. That's easy. The directories of the frugal installations get the tc version number and are removed if they are too many or too old,
Probably I will write a script to ease this job too
My data remain on a separate drive and are not touched
In other words, this is a new way of throw-away-philosophy
