Subject: Re: [PATCH 7/9] tune2fs: confirm dangerous operations

I've tried it out, and I think 5 seconds is enough time.  I'll note
that just hitting the return key will abort the operation, so the user
has to type 'y', return in order to continue.  In fact I will probaby
change the prompt so it looks like this:

Proceed anyway (or wait %d seconds) (y,n) ? <n>

This should make it clear that if the sysadmin is not sure, just
hitting return is enough to cancel the operation.
