Remastering Tiny Core makes sense when certain libraries and modules are needed in core.
But to do the typical remaster for applications does not give much advantage.
Of course it can be done. But...
Everything from tinycore.gz is loaded into memory. You no longer have choices as you do now.
The time to load into memory whether at boot from compressed cpio or from a compressed tar or ziofs/cramfs is not much different. The concept behind Tiny Core is that Tiny Core is the engine.
In the beginning we had thought about offering Tiny Core versions with certain collections of appllications. We decided not to, with not much different load tiime and a hit on ram requiremens (like only having tces) , but to offer many more choices instead.
Use the optional directory ( located under your tce directory ) is highly advantageous. Only place the apps that you need upon each and every boot into your tce directory, place apps that are used on occasion into optional directory, i.e, perhaps, compiletc, or oo2. Then when those apps are needed use appsbrowser File>Install Optional
Note when using appsbrowser, you can download directly to the optional directory by using the Download Only option. When using this option the optional directory will be automatically setup if needed.
For faster load times, using tcz is faster than using tce and, of course, using a PPI is no load time.
