These two packages are incredibly useful for partitoning, and not having them by default on the ISOs is a real shame.
I'm preparing a new MATE ISO, I'll add them.
I prefer using the runit base ISO. Could the base ISOs also be updated?
We have by default ncurses cfdisk on iso, part of util-linux.
I've never used cfdisk before, but I know there are people who use those other two tools. Do you consider cfdisk the be-all-end-all partitioning tool?
cfdisk is pretty a mature piece of software, iirc 26 years development by now.
Since it is part of util-linux, I'd consider it a default partitioning tool, but it is also a matter of taste.
