I didn't. It was created automatically when I installed dracut-core.
Prior to that, it was created automatically every time I did anything
with apt-get which touched the "low level stuff" (kernel, firmware,
microcode, busybox, other tools that live in the initrd, and so on).
Here's an example:
unicorn:~$ sudo apt-get purge dracut-core cryptsetup

0 upgraded, 0 newly installed, 4 to remove and 0 not upgraded.
After this operation, 1,847 kB disk space will be freed.
Do you want to continue? [Y/n]

Gah. It's still inflated.
