Hi T,
You can avoid the need for /boot entirely by adding "GRUB_ENABLE_CRYPTDISK=y" 
to grub.cfg as discussed here:
Read it carefully and see what you think. On that forum they discuss how to 
delete /boot, because GRUB can probe disks and unlock them, although you need 
to put in LUKS password twice. It does work, I can conform, on a computer 
without Libreboot installed. It may be of use to you, as instructions are 
provided which show how to install using the text installer (Debian was used 
but Trisquel has the same process as they have the same text installer). Then 
there's no need for putting /boot on external USB drive. Note, you may need to 
unlock the drive on a live CD in order to add the option to GRUB config file if 
the installer doesn't do it automatically.
If you really need /boot on an external drive one suspects you just change the 
UUID in /etc/fstab to that of some partition on the USB drive. Then copy all 
the files there, and delete the partition that /boot is mounted at, usually 
/dev/sda1 if you install on /dev/sda.

Hope that helps,
