My wish would be to see listing explicit steps because when a lock occurs
it would be possible to report last completed ( or started ) step .
Otherwise , actually seeing a swirling set of characters is itself not much
useful other than showing there is a progress without understanding what is
going on .
If I were able to change anything in FreeBSD , my first choice would be to
change these swirling characters to list explicit names of completed tasks
( or starting tasks which operating system developers would know best
which one is more useful ) .
Thank you very much .
