man 1 eject says -m This option allows eject to work with device drivers which auto- matically mount removable media and therefore must be always mount()ed. I dont think "()" should be here, or some number may be missing. *** $ equery b /usr/share/man/man1/eject.1.gz [ Searching for file(s) /usr/share/man/man1/eject.1.gz in *... ] sys-apps/eject-2.1.5-r1 (/usr/share/man/man1/eject.1.gz) Some times Gentoo patches manpages, so, I reoprt here instead of upstream. Good luck.
changed it to mount(1) to match the previous section which uses umount(1)
