I am not sure where to put it but if you have found a command line sync
tool then you should be able to set us a script do the update at both
login and logout. I know that kde will run anything in ~/.kde/Autostart
every time the user logs in. I am not sure about logout but I bet that
there is some similar mechanism.
Not really the solution that you were looking for but you might checkout
autofs. It uses nfs to mount a shared folder as needed. At work I share
my home folder across a few machines. (It makes passwordless ssh
connections a breeze to set up.)
To be or not to be, that is the question
2b || !2b
(0b10)*(0b1100010) || !(0b10)*(0b1100010)
0b11000100 || !0b11000100
0b11000100 || 0b00111011
255, that is the answer.
