Comment (by s7r):

 I know why it generated an Ed25519 identity in /root/.tor/keys.

 I tried to run:
 # tor --keygen
 Without a --datadirectory argument (I thought this command was actually
 saving the output/data in working directory - where I typed the command,
 in my case ~/workspace/tor, not default to $HOME/.tor/keys).

 Anyway, it was a surprise for me and it didn't strike my mind when first
 opening this ticket, I didn't expect any keys to be generated at all,
 since the --keygen command failed with bug errors. See #16679 which is
 about why the command failed, but yet it still generates files in
 $HOME/.tor/keys.

 This answers a second question: Is it generating unrequested Ed25519
 identity keys? No, it is not. But we should improve the behavior and
 reporting as soon as possible.
