On my long-running debian box, /lib/systemd/systemd is 1.1MiB in size. In /proc/1/smaps, I find the following executable mapping: 55aa05f89000-55aa06076000

On my long-running debian box, /lib/systemd/systemd is 1.1MiB in size.
In /proc/1/smaps, I find the following executable mapping:

So it appears 740KiB has been referenced, 752KiB resident.
There's also the read-only mapping:

Another 148KiB, so 900KiB, a good chunk of the 1.1MiB - though this is with a substantial uptime.
The really disgusting part is all the dependencies; `pmap 1` says 57MiB total, and there's not much anonymous memory to blame.
