NAME

       fs2ram - manage post-mount/pre-mount scripts

SYNOPSIS

       fs2ram action -a [-f] [-q]

       fs2ram action <mountpoint> [-f] [-q]

       fs2ram -h

DESCRIPTION

       fs2ram  manages  temporary  file systems across reboots. Each tmpfs <mountpoint> can be associated with a
       pre-mount script, which is executed  by  fs2ram  at  each  shutdown/reboot  before  the  file  system  is
       unmounted.  The  pre-unmount script must print a post-mount script on standard output, which is saved and
       then run at boot time after fs2ram mounts the corresponding file system.

OPTIONS

       action This option specifies the action to execute. It could be :

              unmount:
                  This action first execute-unmount-script and then unmount.

              mount:
                  This action first mount-only and then execute-mount-script.

              mount-only:
                  This action mounts the filesystem given in parameters.

              unmount-only:
                  This action unmounts the filesystem given in parameters.

              execute-unmount-script:
                  This action executes the unmount script corresponding to the mountpoint given in parameters.

              execute-mount-script:
                  This action executes the mount script corresponding to the mountpoint given in parameters.

       -a     This option tells to do action for each <mountpoint> specified in /etc/fs2ram/fs2ram.conf

       -q     This option tells to be quiet (only warning/error).

       -h     This option tells to display the command usage.

       -f     For the action unmount and  mount,  this  option  tells  to  proceed  execute-mount-script/unmount
              respectively  even if mount/execute-unmount-script failed. This option has no effect for the other
              options.

DEFAULTS

       By default, fs2ram won't make /var/run, /var/lock or /tmp available as ram  filesystems.  Since  sysvinit
       provides a way to achieve this, it is preferable to use it. See tmpfs(5) for more information.

UNMOUNT SCRIPTS

       An  unmount  script  has  to  produce to the standard output the mount script that fs2ram will execute at
       boot. The unmount script takes two arguments. The first one is the concerned mountpoint. The second  one,
       optional,  is  the  options given to the script.  The default unmount scripts are in /lib/fs2ram/unmount-
       scripts/
