Well I can't see how it will help in my use case. I can't think of why
it would be useful in practice, since lsh-make-seed is already being
called with --sloppy by 'ssh-service initialize? #t'.
The only reasons I can think of are ...
- to enable a user at the console to manually reproduce what
'ssh-service initialize? #t' does, and
- to avoid it being reported as a bug
... which is why I didn't report it as a bug.
Re my use case, am I correct in believing that the only way to address
it is to enhance lsh-service with an alternative initialization scheme
that does not require console input?
If so, maybe we should rename the current initialize to ...
INITIALIZE-REQUIRING-CONSOLE-INPUT?
... and add a new one named ...
INITIALIZE-UNATTENDED?
WDYT? - George
