First time impression from an ordinary user
When traveling I take my Pixelbook Go chromebook. At home I use debian or kubuntu. My linux knowledge is average.
I got interested in atomic or immutable linux, because I like the way that chromebooks are low maintenance devices.
So I got myself a laptop in multiboot mode with Origami Linux and Bazzite. Both are fedora atomic variations with extra flavour like a CachyOS kernel for Origami Linux.
I got interested in the story of AerynOS how they do atomic without [yet] being immutable.
Right now, a multiboot installation of AerynOS is not for a beginner.
First I tried to flash a usb with dd. Finally balena etcher worked for me, because my laptop's BIOS is very picky. The text based installer picks the first esp partition it encounters, which will not work if you want a multiboot with separate esp partitions. Fortunately gparted is included in live usb. So I temporarily removed the boot flags of partitions the installer should not pick.
Wow the installation process is simple and fast. Also the booting. I boot from refind into the systemd bootloader. The OS is as stable as Fedora atomic. Yes there are a few unfinished edges. What I find most lacking are packages in the moss repository. This is understandable.
If I compare Origami Linux with Cosmic desktop and AerynOS Cosmic, the installation of system packages [rpm-ostree] is slow in Fedora, which AerynOS solves with moss atomic installations. On the other hand Fedora has more packages and the integration of stuff like topgrade and brew.
Will I be using it as a daily driver? Not yet. Who knows what the future will hold. But AerynOS is surely a promising distro to watch and try out.
