I wasn't that well informed. i've read up on the issue. Lets now
consider following


On desktop should be gone by now, but formally Intel slashed
production of 386 in 2007 (according to wikipedia). Dapper is still
supported until 2011 and I see a lot of 386's still staying around as
slow, small "home" servers.


The cange will negarivly affect old PC users, old PC server's and
embedded platforms. In addition did anyone confirm 586 instructions
are fine with Via & AMD (i hope they are fine on modern Intel chips)?


Rebuild the whole archieve...... Did anyone try that with i586? I
would like to see a rebuild of the archive from scratch. I bet there
will be quite a few FTBS.

what else:

This change will probably result in a new architecture in the archive
because of Old PC's, Old servers and Embedded systems which are still

On the other hand we can be all hype and force Old PC's, Old servers
and Embeddeb systems to use Debian =DDDD

In conclusion I'm against the change until I see a full rebuild of the
archive and some *significant* real-life figures why whould I switch
from 386 to 586.

With best regards
