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

[Brian Murray]

casper is not installed on the target system during the installation
process and afaict usb-creator doesn't require capser or lupin-casper so
I'm really not sure what happened to your system.

Additionally, compcache (according to the casper changelog) should only
be used on systems (running casper) with less than 512MB of ram.

casper (1.232) lucid; urgency=low

  * bump compcache size to 50% on live images for machines with less than
    512MiB. This makes sure we don't hit OOM errors on systems with only
    256MiB of RAM.

Title:
  casper configures system to use 50% ram for compressed swap post
  installation

Status in “casper” package in Ubuntu:
  New

Bug description:
  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.
