Man page generation is generally very slow. I prefer to use -Dman=false when developing systemd, and only build specific pages when introducing changes. Those two little helper tools make it easy: $ build/man/man systemd.link $ build/man/html systemd.link will show systemd.link.8 and systemd.link.html from the build directory build/.
