## Wiping RAM at shutdown to defeat cold boot attacks.

## RAM wipe is disabled by in virtual machines (VMs).

## RAM wipe is omitted in virtual machines (VMs) by default because it is
|
|
## unclear if that could actually lead to the host operating system using
|
|
## swap. Through use of kernel parameter wiperam=force it is possible to
|
|
## force RAM wipe inside VMs which is useful for testing, development purposes.
|
|
## There is no additional security benefit by the wiperam=force setting
|
|
## for host operating systems.

#GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT wiperam=force"

|
## Kernel parameter wiperam=skip is provided to support disabling RAM wipe
|
|
## at shutdown, which might be useful to speed up shutdown or in case should
|
|
## there ever be issues.
