I use rEFInd as my boot manager and sometimes I like to dual boot a new linux distro (just to try out) which I install with a live USB. Unfortunately, after installing, GRUB has always taken the reigns and it becomes a slight inconvenience to get back to rEFInd every time.
Is there some trick that can request grub not to install?
[What prompted me to ask was I tried KaOS yesterday, and during installation it asked what bootloader i wanted and included the option for ‘none’.]
Another option is to avoid the installer entirely and install from a live environment using chroot and whatever your distro’s installation bootstrap tool is. I started using this method to install Debian on ZFS root using this method for a while and it’s become my go-to method for installing most distros as it gives you the most control over the resulting OS. It will also often take some distro-specific knowledge but is also a valuable learning opportunity.
