Easy deployment and maintainability with union file system

Merging file system with linux

Thanks to Linux kernel, there are differents distributions compatible with differents union file systems.
Debian, one of them, that can be highly customizable easely, and get a package manager which works very well and with probably all packages available for linux :)

Some other distributions of linux can be run on live CD, USB stick and also directly on RAM, Slax is one of them, which offer also AUFS (a union file system) and tools to used it...
Another alternative can be linux live kit...

*.sb modules example (AUFS file system mergable blocks) :

inside *.sb modules (sudo.sb here) :

Wine can also be used to run some "not ported" apps, that only run on windows, like MT5 application with different accounts...
Postgres can also be installed this way and so on...

From my point of view, for this kind of specific application, this way is far easier, flexible, clear and powerfull than Docker !

And there is also far more possibilities...
