How to Enable su root For a Normal User in FreeBSD

root@freebsd:~ # su - andre

When you've made modifications to a file in vi(1) and then find that

you can't write it, type ``<ESC>!rm -f %'' then ``:w!'' to force the

write

This won't work if you don't have write permissions to the directory

and probably won't be suitable if you're editing through a symbolic link.

If you have a CD-ROM drive in your machine, you can make the CD-ROM that is

presently inserted available by typing 'mount /cdrom' as root.  The CD-ROM

will be available under /cdrom/.  Remember to do 'umount /cdrom' before

removing the CD-ROM (it will usually not be possible to remove the CD-ROM

without doing this.)

Note: This tip may not work in all configurations.
