static unsigned long shmem_default_max_blocks(void)
	return totalram_pages / 2;

which probably makes sense for an installed system, but not for an
installer.  We can however do this early at boot:

mount / -o remount,size=$(( $(grep ^MemTotal: /proc/meminfo | { read x y z; echo $y; }) * 1024 )

notably before unpacking .udebs, S15lowmem would probably be a fine
place for this? (it notably already does the computation trick)
