Name

       pmvarrun - updates /var/run/pam_mount/user

Syntax

       pmvarrun -u user [options]

Description

       A  separate  program  is  needed  so  that  /var/run/pam_mount/user  may be created with a
       pam_mount-specific security context (otherwise SELinux  policy  will  conflict  with  gdm,
       which also creates file in /var/run).

       pmvarrun is flexible and can run in a number of different security setups:

   root-root
       When  pmvarrun  is  invoked  as  root,  /var/run/pam_mount's permission settings can be as
       strict as needed; usually (0755,root,root) is a good pick as  it  gives  users  the  debug
       control  over their refcount. Refcount files are given their respective owners (chowned to
       the user who logs in).

   user-user
       When invoked as the user who logs in, /var/run/pam_mount needs appropriate permissions  to
       create  a  file, which means the write bit must be set. It is also highly suggested to set
       the sticky bit in this case, so other users do not tamper with your refcount.

   root-user
       Some programs or login helpers incorrectly call the PAM stack in  a  way  that  the  login
       phase  is  done  as  root  and  the logout phase as a normal user.  Nevertheless, pmvarrun
       supports this, and the same permissions as in root-root can be used. While  the  user  may
       not  be  able to unlink his file from /var/run/pam_mount, it will be truncated to indicate
       the same state.

Options

       --help, -h
              Display help.

       --user user, -u user
              User to handle, must be a valid username.

       --operation number, -o number
              Increase volume count by number.

       -d     Turn on debugging.

Files
