Could be. For that, I'd probably just advise making sure that the user is in 'staff' class and bumping datasize-cur, and not worry too much about the fact that limits are increased for everything. > Scott, I believe you use the .desktop file to launch FreeCAD, correct? > If so, you will probably want to make a copy under > ~/.local/share/applications that launches a wrapper script, as sthen@ > suggests. There's no path to the binary in org.freecad.FreeCAD.desktop so you don't actually need to touch that file, you can just leave it as packaged. Instead set your own PATH (e.g. in .profile or .xsession) to include ~/bin or similar ahead of /usr/local/bin, and add a wrapper script there. -- Please keep replies on the mailing list.
