Disk quota installation


  1.  Tasks

  The quotacheck utility will check all directories of a filesystem and
  compute the amount of disk space and the number of files/directories
  for every user and every group. The results are stored in the
  quota.user and quota.group files.  These files are located in the root
  of each file system.

  This command obviously take a while to execute. Once executed, the
  files quota.user and quota.group will be maintained in real time by
  the kernel.


  2.  User and group quotas are independent concepts

  It is possible to install disk quotas only for users and not for
  groups or the reverse. If you do this, then only quota.user or
  quota.group will be produced.
