[Bug 933712] [NEW] casper configures system to use 50% ram for compressed swap post installation

[Ben Howard]

Public bug reported:

When installing from live-cd or if Capser is installed, it leaves
/usr/share/initramfs-tools/conf.d/comcache with a value
'COMPCACHE="50%"'. This means that a user will loose half of their RAM
to a compressed swap device on kernel initramfs generation and reboot. .
In my opinion this is a _very_ poor user experience.

A work around is to boot with "nocompcache" as a kernel option. However,
requiring a user to boot with "nocompcache" is beyond many users and
will surely frustrate power-users and developers.
