Bug#1069791: console-setup: Build larger console fonts for HiDPI/accessibility with future 6.9 kernels
My apologies for missing the existing bug scrolling through the list. There were a lot of them to sift through. I may see if some of them have been incidentally fixed as far as I can tell.
I understand the eventual goal for the kernel folks is to rid themselves of CONFIG_VT all together, so I realize this is a stopgap. Even so, could you try to include a DejaVuSansMonoBold font as well? I'd appreciate it if it's possible as I can personally read a smaller heavyweight font and it'd really help debugging servers with my portable display.
Obviously the long-term solution is some userspace alternative that does the same thing probably using cage and some restricted tabbed terminal maybe? Hmm. I dunno if that's even on anybody's radar any sooner than forky.
