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/
