#illumos — Public Fediverse posts

@mhoye

Right away this sounds like a task for a "declaratively defined" distros, based on nixpks, guix or any other similar toolkit. There are tools, but no ready-made distro that does that, as far as I know.

The second set that comes into my mind is the "immutable" distros that utilises CoW FS, snapshots of the initial state and some machinery to change it. I'm most familiar with the SUSE famliy, thus I'm thinking of MicroOS, Leap Micro and Aeon Desktop - with snapper and transaction-update one have an access to the post-install state and may replay it anyware.

This kinda similar to what FreeBSD and illumos distros achieve with the ZFS and a "boot environment" concept (administrated via bectl/beadm).

And in the devops world it'd be a packer image applied to a new device.

A wild #blog post appears!

I discuss a new #research publication: an empirical evaluation of the #OpenBSD -fret-clean flag. We examine the history of the mitigation, measure its costs, and deliberate whether or not it is worth keeping.

Worth the read if you like security and/or compilers.

Successfully ported the complete #LLVM stack (version 19.1.7, including llvm's binutils, clang, ldd) to #Solaris 11 Express (snv_151a) #SPARC. This build of #Solaris works on #SPARC machines that Solaris 11 GA (and later) do not support (example: sun4u workstations and servers), as well as machines that #Illumos does not support completely. This may allow for #Zig and #Rust to be ported to this version of Solaris on SPARC. Complete source archives, build instructions, and signed binaries in SVR4 package format (and soon, IPS) will be available for download. #Solaris #SPARC #retrocomputing #Illumos #Sunmicrosystems

The year is 2024 and bpftrace crashes when there's an extra whitespace.

bpftrace is DTrace 2.0? DTrace my ass. I've never seen DTrace crash because of an extra whitespace.

Hell, I've never seen DTrace crash, ever.
