glaucus-s6-x86-64-v3-20241026

What's new?

• glaucus now runs on real hardware!
• This is a stage 3 release (native compilation after cross compilation; previous releases were at stage 2 which meant they were cross-compiled only)!
• limine is now the default boot loader and manager!
• neatvi is now the default text editor!
• reflex is now the default lex implementation!
• faillog, last, lastb, lastlog and w are now all running securely under musl libc thanks to utmps!
• DT_RELR support was enabled, and has resulted in further size reduction!
• rad (glaucus package manager) has been improved with more functionality being fleshed out.
• The bootstrap process has been further optimized resulting in a reduction in the number of packages being used.
• CachyOS kernel and modules are being used for this release!
• Updated cerata

What's new?

A summary of changes that took place:

glaucus-s6-x86-64-v3-20231002

What's new?

A summary of changes that took place:

• A glaucus ISO is finally being released for the first time! This marks a new huge milestone for glaucus after years of hard work and dedication. The ISO supports booting in both BIOS/MBR and UEFI modes, but is still in beta phase and in read-only mode (overlayfs for read-write mode and EROFS support have been proposed to booster and will hopefully be provided in the following releases)
• glaucus is now self-hosting, being able to bootstrap itself under itself! This is also another huge milestone, and has resulted in a reduction in the number of packages being included in the bootstrap phase, making it faster and more minimal
• libudev-zero is now the default libudev implementation
• mdevd is now the default udevd implementation
• muon is now the default meson implementation
• mold is no longer the default linker (see this and this)
• OpenBSD M4 is no longer the default M4 implementation (autoconf requires GNU M4)
• Arch Linux kernel and modules are being used for this release
• Updated cerata

glaucus-s6-x86-64-v3-20230428

What's new?

This release is a modest attempt to follow a regular release cycle for glaucus.

A summary of changes that took place:

• radula was rewritten in Nim (previous version was in Rust), reasons for this include:
  • code is reasonably more readable (more so than the Rust version)
  • much less LOC even with more features added (compared to the Rust version)
  • code is written in a reasonable amount of time (much less than Rust version, again the rewrite itself took about a month, but the speed at which newer features were added is like 4 - 8 times faster than in Rust, probably because I am not proficient in Rust even after a year of using it...)
  • uses less system resources (1/3 of what the Rust version uses)
  • much smaller executable size (200 to 300 KB) (compared to the Rust version 3 MB)
  • can be built using glaucus's existing toolchain because Nim transpiles to C; thus, making use of the optimized toolchain glaucus uses (unlike Rust which is very hard to bootstrap, and does not work all that great with shared musl...)
  • slightly faster (parsing cerata is around 6 - 20% faster overall) (this is probably because I am not proficient with Rust even after a year of using it, but then again I've only been writing in Nim for a month...)
• glaucus's toolchain now uses mold by default, and all executables (with the exception of the Linux kernel) are being linked with it
• glaucus now uses yash as the default shell for interactive use instead of oksh for the following reasons:
  • more strict POSIX compliance compared to oksh
  • much more user friendly compared to oksh
  • about 50% the size of bash and only slightly bigger (10 - 20%) than oksh
  • about 30 - 40% faster than bash and has identical performance to oksh and loksh
  • multiline support, which is not available in oksh
• glaucus now uses OpenBSD M4 as the default M4 implementation
• glaucus now uses BLAKE3 as the default hashing algorithm instead of SHA-512
• Update default ASCII art
• Updated cerata

This release is more stable compared to previous releases but it still is not production ready.

glaucus-s6-x86-64-v3-20221011

What's new?

Wow, 2 years have passed already and glaucus is still going strong as ever!

Needless to say, a lot has changed. The following is a summary of changes that took place:

• radula (glaucus's package manager written in Rust) is now fully capable of building a cross compiled glaucus system!
• glaucus's toolchain is now more refined and mature
• s6 is still the default init system (finit was removed completely)

This release is more stable compared to previous releases but it still is not production ready..

glaucus-bennettae-finit-x86_64-20200930

What's new?

Decided to post this release after a year has passed since the previous release.

During this year a lot has changed, glaucus's build system changed multiple times until it became what it is like today:

• first it was a completely cross compiled system that only built for one architecture
• then it changed to an isolated sandbox build (similar to LFS) that cross compiled a native chroot and built everything inside it
• and finally transitioned back to a completely cross compiled system with a revamped toolchain design that allows building for multiple architectures and with different optimization flags

This release is by no means stable and shouldn't be used for production use, it's only here to show that the project is still alive and kicking.
