[tor-talk] Tor Browser Bundle update mechanism for Unix

[anonymous.coward at posteo.de]

Dear list,

can someone explain how the TBB update mechanism works precisely with 
Unix operating systems?

Especially I´d like to know, does it use a shell script for updating the 
TBB?
If yes, will the shell script be downloaded first or is it already 
existing?

Is the binary Browser/updater the program that processes the update?

I´m asking, because I use Mandatory Access Control to confine the 
browser bundle and need to know how the update mechanism may require to 
access the TBB directory and files.

Thanks
