Install vs Mount - Core Concepts

[oleg]

On the main page "Getting Started with Tiny Core Linux - Core Concepts" there are 2 distinct modes: "The Second Mode of Operation: TCE/Install" and "The Third Mode of Operation: TCE/Mount".

These might be silly questions, but...

How one distinguishes between these two?

AppBrowser has only "Install" and "OnDemand" buttons. When I install is it mounting or installing?

Is the command "tce-load -i" mounting or installing?

How to do either way?

Where to read about tce-load command?

Another problem which I have is monitoring free memory (I use 'top' or 'free' commands).
Say I have 47M consumed. I install opera10. Memory consumed jumps to 53M. If I start opera memory jumps to 114M. But when I exit from opera the memory reduces only to 104M.
Is there a way to uninstall/unload programs ?

The appbrowser "Install Options" controls whether some or all programs are ram loaded or mounted.
It does this by managing the copy2fs.flg and copy2fs.lst files.

[oleg]

Does tce-load use the same copy2fs flag files?
Does copy mean installed and non-copy mean mounted (default)?
What are options for -i and -w for tce-load?

[curaga]

Yes, tce-load honors them. Copy is the same as install.

-i install, -w wget.

This command may be helpful

Code: [Select]

sudo /usr/sbin/cache-clear
It does not "uninstall/unload programs" as requested but does clean up cached files created by an application.

On my test system the kernel does not deal with cached files as well as cache-clear.  The kernel usually only partly cleans up in the way you observed with Opera.  I obtained some helpful information in this post:

? would it make sense to add a button to App Browser ?

"UNLOAD/OFF" application or some such feature?

Not remove it from "optional" - rather clear that space in memory and make it unavailable to aps unless "reloaded"?

Also, does opening a 2nd Desktop start a "new instance" of a fresh ram image such that aps run in Desktop #2 are isolated from Desktop 1? If not, perhaps something at "boot" to accomplish this or am I reaching for a royal pain to code?

Opening a 2nd desktop is simply a visual effect.
You might want to look into 'chroot'.
