tools to preserve tmpfs contents across reboots

 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.
 .
 This package provides two pre-unmount scripts designed to preserve folder
 structure and file permissions across reboots: this is needed to allow
 hierarchies such as /var/cache or /var/log to be mounted as tmpfs.
