Ah, that makes a lot of sense. However, if I *was* running the prefix |
| 26 |
tree on my base system (assuming the @system changes were dealt with |
| 27 |
somehow), I should be able to avoid altering that tree. |
| 28 |
Alternatively, if I ran a department server where several users had |
| 29 |
their own prefix, there could be a shared tree in a central location. |
| 30 |
If a new user wants to start a prefix, they should be able to do so |
| 31 |
without checking out a new snapshot. If the changes were made under |
| 32 |
"${EPREFIX}/etc", this would work, then just wipe out the changes |
| 33 |
instead of calling `emerge --sync` (since presumably the sysadmin had |
| 34 |
been keeping the prefix tree synced already). |

Also, in Jeremy's bootstrap-gentoo post [1], I think you need |
| 37 |
|
| 38 |
$ ./bootstrap-prefix.sh $EPREFIX latest_tree |
| 39 |
|
| 40 |
before |
| 41 |
|
| 42 |
$ ./bootstrap-prefix.sh $EPREFIX portage |
| 43 |
|
| 44 |
in code listing 1.3, otherwise there's no local tree there to do all |
| 45 |
this editing on. |
