- If you are concerned with the space used by the .udeb itself, under
  very low memory conditions the lowmem package already asks the user
  to choose which udebs to enable. TBH, "lowmem" nowadays doesn't care
  about a few dozen KiB :)

- If you are concerned with possibly large page cache usage, well it's
  up to the Linux kernel to flush when it feels obliged to, and at this
  point the swap is enabled already anyway.
