Indeed:
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)
