Does removing an app in LIVE mode free system resources?
 

RAM?

If a read-only boot is static, what does it mean to remove an application in live mode?

You don't provide a lot of detail, but, to the best of my understanding, if said application is not in use, it's not using RAM; it's just taking up disk space. Accordingly, removing it would have no effect.

Thanks for sharing your opinion Frank. Ubuntu is released read-only with the option to install, & I'm just trying to figure out how that works. When you write to a read-only system it goes to ram, but when you delete?

I also use a derivative that works differently & I am certain there no ram is freed.

I am probably seeking a culture of read-only Ubuntu users.

You can enable persistence via the use of an application such as rufus which has the option that allows you to configure a partition on your SD card or USB stick.

The problem with Live media is you can't really modify it like a normal install. Usually there is a compressed file that is the live state filesystem. One might be able to take that compressed image and modify it then return it to exclude a "Program".

As posted it does not free any resources but depends on the live distribution. Most live versions use a method to combine RAM and CD (or flash memory) to look like they are one (aufs or EWF). The application itself is not actually in RAM. Some live versions have an option to load everything to RAM but that usually isn't the default.
