I have recenty set up a Kali live operating system with a LUKS-encrypted data persistence partition, and used it for a while. Unlike Tails, fortunately Kali Linux makes use of a ISO9660-formatted partition for system files (it does not feature the kernel update facility however). Anyway, my question is the same as for Tails: if I lend my USB key running Kali to an evil Penguin, am I sure to use it again afterwards?

If I lend my USB key containing Tails Linux to an evil Penguin, am I sure to use it again afterwards? Is my LUKS key safe? There is no need for an evil Penguin to force or trick me to tell him my LUKS passphrase (as Tails website warns), he only needs to ask me to use my USB key for just a short while.

An evil Penguin’s idea is to inject a script into the Tails filesystem which is able to reveal the LUKS master key – and eventually send it by the network.

As a debianized Penguin, some time ago I reviewed Secure-K OS, a commercial Linux-based live operating system meant to be run from a USB key and “developed with security in mind”, according to its developers. Good news is that the upstream developers have in the meanwhile open-sourced the architectural technology upon which Secure-K OS insists and a Community edition of the operating system itself on GitHub, named Open Secure-K OS.

As the name suggests (Secure Key), Secure-K OS is a live operating system, based on Debian 9 Stretch, meant to be run from any USB key and “developed with security in mind”, according to its developers...

Raspberry Digital Signage is an operating system designed for digital signage installations on the Raspberry Pi: it displays a full-screen browser view restricted to a specified (web) resource.

Raspberry Digital Signage 11 has been released today, which comes with the latest raspberrypi-bootloader, so that it is compatible with the new Raspberry Pi 3 b+ board line.

Marco Buratto has released Raspberry Digital Signage 10.0 today. The underlying operating system has been moved to Raspbian Stretch; the overall performance is sensibly better and HTML5 videos play a lot smoother.

Raspberry Slideshow is a Raspberry Pi operating system focused on quick-to-set-up media slideshows. It can play all media contained in an inserted USB key, fetched from a Windows (Samba) share, from a Webserver or FTP server.

Raspberry Slideshow 9.0 has been released today, featuring a big update of its underlying Raspbain Jessie base operating system. As of now, all Raspberry Pi range of micro-computers is supported.

Raspberry Digital Signage 9.0 comes with Chromium v.56 (featuring advanced HTML5 capabilities, Adobe Flash support and H264/AVC video acceleration), so you can display more attractive resources, more easily. Digital signage page can be retrieved from the Internet, LAN or even from localhost (a www folder inside the Raspberry Pi’s SD card). To simplify the management of the internal site setup, RDS 9.0 comes with WordPress already installed.

Raspberry WebKiosk 6.0 has been released today with a complete update of its underlying operating system, from Raspbian Wheezy to Raspbian Jessie Lite (a Debian Jessie derived OS for the Raspberry Pi microcomputer). Raspberry WebKiosk is designed for web kiosks and multi-user web workstations (think about using it in cafès, offices, schools, hotels, hospitals, libraries) with the Raspberry Pi base, where people can surf the web with a normal browser. It’s a port of the more powerful Instant WebKoisk system for PCs.

In the first part of this article I’ve covered system installation, first login and GNOME/XFCE desktop environments usage and I’ve had a brief look at the init system of TrueOS. In this second part I’m reviewing TrueOS’ most exclusive and distinctive feature, the updates’ management.

A Penguin tries out TrueOS, formerly PC-BSD, and compares it to his beloved Debian GNU/Linux desktop..
