@ytc1 @DenOfEarth @aka_pugs I know.

And espechally in #ScientificComputing a lot of researchers loved working with #SunMicrosystems and when #Oracle took over that relationship got sour'd instantly due to #Oracle #CEO #LarryEllison...

-> infosec.space/@kkarhan/1146825

One of the big successes of #Sun was that they basically declared a unilateral "ceasefire" in terms of #IP & #Patents re: #OpenSource. Whereas Oracle didn't seem willing to honour that.

  • Without that cooperative atmosphere we saw #OpenOffice devs literally forking off into @libreoffice and projects like #illumos and @openzfs scramble to save what was OpenSource'd and also rescue that.

Obviously #Linux with it's #GPLv2only-Kernel and most of it's Userland could not get 'closed-sourced' like #OpenSolaris which instantly got stomped out by Oracle as they wanted to sqeeze #Solaris for profits and milk their clients in typical Oracle fashion...

Now granted, I do know someone who for most of their life made their money dealing with the intricacies of setting up #postfix, #sendmail and #courier #MailServers on Solaris and if I ask said person about that they give me a kilometer stare, so OFC like a #SysV - #Unix systems Solaris and #SunOS really are one of the reasons #WindowsNT won the "#WorkstationWar" and why - if anyone - #Apple won the last "#UnixWar"...

  • Still I do am sad that I declined that #sysadmin position at a leading research center I'm not at liberty to name and I do know there's OFC still some critical infrastructure running even older Solaris servers...

Cade in point, #OpenSolaris did have avid users just below that range, and a lot of #ScientificComputing used it, as they previously used #IRIX. And #Sun being #OpenSourve-friendly was the right direction...

Linux Moves to Remove System V File System

Linux developers are planning to remove the aging System V (SysV) file system from the kernel. SysV, once widely used in early Unix systems, is now largely obsolete, with modern alternatives like ext4 and XFS dominating. The removal aims to streamline the kernel and reduce maintenance burden. While some legacy systems may still rely on SysV, its relevance in modern Linux is minimal.

SysV filesystem is being removed from Linux 6.15

In the old Unix days, there was a filesystem that implemented the Xenix FS, Coherent Unix FS, and SystemV/386 FS. It allowed file organization and access that provided the data storage service that allowed applications to access mass storage and its contents, including files and folders.

The ex-maintainer of this filesystem support for Linux systems had orphaned the filesystem maintenance back in 2023, when the maintainer said that there was no way to test it, with the possible removal slated in the future.

The future has come, and Jan Kara from the SUSE team has pushed a commit to the VFS git that removed all code for the SysV support for Linux, which confirms that, starting from Linux 6.15, you won’t be able to access these legacy filesystems. This is because, back in 2023, Google’s Linux kernel fuzzer, syzkaller, has automatically reported a bug in SysV where the sleep function was called from an invalid context.

As nobody is using this filesystem in their Linux installation, it’s safe to remove this filesystem support from the kernel. This only affects computers that have both Linux and a legacy Unix system that uses this antique filesystem installed, but the amount of such computers is very small.

Once Linux 6.15 gets released, you won’t be able to use any partitions that use this filesystem.

Will Damron's read of the audiobook of Cliff Stoll's "The Cuckoo's Egg" is excellent.

While the book is required reading or listening as a historical record for anyone interested in Information Security, it's a thoroughly enjoyable a thriller. Though much of the technology mentioned is familiar to folks who are thinking I'm about to call them old, it's unsurprising how much remains painfully pertinent today, yet pleasing how a few things have improved significantly given only a few decades.

While some library networks such as the DoD MWR will keep you waiting months for one of their few copies, Fairfax County has unlimited copies of the audiobook.

I hope @AndresFreundTec is keeping good notes on his adventures with xz/liblzma.

@cherti: #Debian Unstable on most desktop-ish devices. Debian Stable releases on all servers.

An occasional #Kali (Debian Testing based) here and there and, if I really need some of their Python stuff, Raspberry Pi OS (Debian derivative on armhf, add-on repo on arm64), despite I clearly prefer Debian on the Raspi, too.

Also one IPv6-only #Devuan VM at @ungleich for getting a feeling for Devuan. Still prefer #SysV or #OpenRC on Debian. #nosystemd

#SailfishOS (RPM-based) on the mobile phone.
