There is not an ISO provided without desktop mostly because it would need an installer from terminal. For a headless installation the available options are rootfs-base archive and the docker image.
I don’t think we understand each other here: are you suggesting that there must be a desktop to use a graphical install? It is possible to graphical install with calamares a system without desktop.
Typically, I rent a VPS, connect with VNC and install a minimal system graphically, then ssh only.
Calamares installs by cloning the squasfs which runs the ISO image. Either it is not possible or I don’t know how do what you say with Calamares plus it has not been a priority for openmamba so far.
Yes, I think you’re right. I was mistaken about Calamares, I apologize.
I would like to use openmamba as a server OS, but I need a more minimal install solution due to my current provider’s limitations on ISO size and storage, and lack of graphical acceleration.
For anybody which might be interested I explain in short (for advanced users and untested) how to start to to manually install a minimal distribution of openmamba:
boot any Linux OS with networking
use i.e. curl or wget to download the openmamba rootfs-base archive from the download page
initialize the destination storage by creating the partition table (GPT or MSDOS) and a FAT32 EFI boot partition (2-300 MBytes) and an ext4 partition
format the partitions respectively with the mkfs.vfat and mkfs.ext4
mount on some mount point the O.S. partition (ext4) and bind mount the boot partition at /boot, aso bind mount /dev,/sys,/proc,/run from the running O.S.
run chroot to get an openmamba chroot shell in the O.S. partition
install the kernel (dnf install kernel-mamba-x86_64)
.
