Re: setup takes a long time

The setup program does seem to take a long time, even when it just
means "update" and even when there's nothing to update. Here's what

Try this with 'ts' from moreutils, e.g:

I can kind of see the point of autorebase and update-info-dir, but why
revisit texlive every time, and why all the zp stuff, every time? Why

These tasks are supposed to identify when they have no work to do, and do nothing quickly. It seems that is not always the case.

does setup explore McShield and McAfee? Incidentally note the switch
-m. Without it, checking sha1sum's I guess provides some kind of
protection, but it's incredibly time-consuming and seems quite
unnecessarily to cover much more than the files downloaded, even the
entire resource? In the presumably very rare event of a broken
download, could the update not more simply just abort?

--local-install could indeed use some improvement.

Note that the scan is also used to filter the list of packages, so (without --mirror-mode) we don't offer for installation packages we don't have the archive for...
