I am needing TeX Live in a system with limited space. Ticking out
Install font/macro doc tree and
Install font/macro source tree in the installer helps a lot already. However, I wonder if there is some sensible way to exclude all the fonts from the install also. I am mainly needing fonts that do not come with TeX Live anyway. So it seems to me like a common sense to completely rely on system fonts. (Please be free to point out disadvantages of the approach.)
I know I could do minimal install and then add packages one at a time when need arises. However, I wonder if I could spare myself from the hassle, if there is a way to exclude the distributed fonts and use system fonts.
