I try a last configuration before move on Debian (where encryption can be
assist with the installer...)
davidnotcoulthard: thanks for precision !
a_slacker_here : yes I read about 40 tutorials or guide for encryption but no
one explain better than this one
https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system
but it's for Arch distribution. I try to adapt this tutorial to Trisquel.
Maybe it's ok now, I undestand a lot of LVM, LUKS and cryptsetup BUT it's
very hard for a new GNU/Linux user to configure alone the system after
installation.
I would a LVM configuration but don't know how to configure so I just make a
simple encryption with LUKS and cryptsetup.
If I success to install, no doubt that I will make tutorial on Trisquel
manual. "If"... ;)
