Debian Project                                   April 16, 2001                                           ZUM(1)

zum  reads  a  files  list on the command line and attempts to perforate these files.  Perforation means,
       that series of `0' bytes are replaced by  lseek(2)s,  thus  giving  the  file  system  a  chance  of  not
       allocating real disk space for those bytes.

       If  you zum under /boot, where your kernel image lives, your system will become unbootable unless you run
       lilo again.
