Control: clone -1 -2
Control: reassign -2 lowmem
Control: retitle -2 lowmem: delete graphical terminal related files in lawmen state
Control: merge -1 -2

Hi,

Then I believe the following patch will remove unnecessary files when the
memory is not enough.

Subject: [PATCH] Delete graphical terminal related files when mem is low

We delete those files here because lowmem_debconf is invoked in
debian-installer-startup and only one instance of it is started,
preventing any race conditions where multiple instances of
debian-installer are started on multiple consoles.
