THE CODE IN THIS PAGE IS HORRIBLE AND DISGUSTING!!!

###Scenario

We have two laptop: a big one and a netbook and we need to share a tomb with personal settings and data.

###Description

unfortunately, we can't just use a "shared" tomb, because tomb cannot be mounted by more than one computer. Furthermore, tomb has (still) no way to use a lock. So, we need to do it ourselves with an external lock (just aside to the tomb).

What we do is (periodically):

acquiring the lock

mounting the remote tomb

using unison to do sync

unmounting

releasing the lock

###The HORRIBLE code

####### START SESSION SCRIPT
export   imgpath=`zenity --file-selection --text='Seleziona il file da cui   estrarre la chiave' --title='Seleziona un file immagine'`
tomb exhume $imgpath /tmp/local.tomb
if ! tomb open /path/to/local.tomb -k /tmp/local.tomb.key; then
    wipe -f -s /tmp/local.tomb.key
    zenity --error --text='Non sono riuscito a montare la tomba!' --title='Orrore!'
    return 1
fi
zenity --notification --text='Tomba locale montata correttamente'
if sshfs remote.server:/ /local/mountpoint/; then
    tomb open /local/mountpoint/remote.tomb -k /tmp/remote.tomb.key
    wipe -f -s /tmp/local.tomb.key
    zenity --notification --text=zenity --notification --text='Tomba remota montata correttamente'
else
    wipe -f -s /tmp/local.tomb.key
    zenity --error --text='Non riesco a raggiungere il server remoto!' --title='Orrore!'
    return 1
