(1) If a user installs sbcl for the first time, there is no previous copy. |
| 6 |
(2) The previous copy (if exists) can be very old, contain bugs etc. The |
| 7 |
build process on users' computers will be not reproducible: if some user |
| 8 |
reports a bug, we don't know which version [s]he used for bootstrapping. |
| 9 |
If we ask him/her, reproducing the bug still becomes more difficult: first |
| 10 |
rebuild the urer's previous version (by the way, using which |
| 11 |
previous-to-previous version?) and only then try to reproduce the user's |
| 12 |
immediate problem. |
