Distinct features

As you might expect there are few considerable incentives to use Porteus as your DevEnv:

  • It is portable;
  • It might be launched on any host;
  • It is a lightweight version of Linux;
  • It might be loaded directly into RAM (!)

Of course it is not a silver bullet, but sometimes it is useful to utilize its peculiar advantages.

This article might shed a light on a much attractive Porteus' feature: its capability to load into RAM of your PC when all data on your HDD stay detached. It might be defined as completely non-intrusive installation of UNIX OS.

Comparison with other live-USB distributions

There is an abundance of similar by main features live-USB Linux distributions, but the Load to RAM is a killer one:

  • OS allocates in RAM, thus:
    • it allows to do all what you want to do on incredible speed;
    • it prevents USB-stick damage by writing incremental changes;
    • it grants you permission to modify it manually.

As an opposite experience I have had Ubuntu USB-stick which was similar by functionality and it was completely ruined after ~70 PC's boot-ing. Seems like incremental changes writing demolished it. And in addition it is unavoidable there.


Suppose it is enough to ensure you to make your own Porteus live-USB and take a challenge of total portability.


Set all stuff on the places

Open root terminal session

Mount partition with Porteus


Porteus saves incremental changes in .xzm format.

# save-changes /mnt/sdc1/porteus/optional/extension_001.xzm

Where /mnt/sdc1/porteus/optional/ is a path to your Porteus Live-USB, and extension_001.xzm is a filename itself.

Edit config:

# nano /mnt/sdc1/boot/syslinux/porteus.cfg


Try to configure <CapsLock> as an additional <Ctrl>:

/usr/bin/setxkbmap -option "ctrl:nocaps"
/usr/bin/setxkbmap -option "caps:ctrl_modifier"
