On laptops I encrypt /home /tmp and swap. /var/tmp is a symlink to /tmp
and If the laptop has mysql or postgresql loaded /var/lib/postgresql is
a symlink to /home/postgresql. Of course if you use mysql change the
symlink accordingly.
This way you have access to the operating system and have fsck at your
disposal. Of course with my setup booting the laptop requires me to
enter 3 passphrases in order to mount the encrypted partitions.
I do not know if it is possible to resize an encrypted partiton. Thus
you need to know in advance how much space you need for the partitions.
