Maybe the benifit is good for you. Those metadata directories in the |
16 |
tree are important because generating portage metadata is costly in |
17 |
terms of time. Thats WHY we do it. |
18 |
|
19 |
When you exclude those directories ( or all of metadata/ ) you are |
20 |
merely moving the cache time from emerge --sync to emerge <blar>. |
21 |
Portage will notice the stale cache and regenerate the metadata on the |
22 |
fly. As noted earlier, this generation is SLOW. Maybe you notice, |
23 |
maybe you do not. It really depends on whether the queries you run |
24 |
against portage hit the areas that lack on-disk metadata. |
25 |
|
26 |
For extra fun, try rm -rf /var/cache/edb/dep/usr, then an emerge --regen |
27 |
and tell me it's fast ;) |
28 |
|
29 |
As for the emerge -S bit, it won't be any faster. It still iterates |
30 |
over the whole tree, and once again, portage will generate the metadata |
31 |
locally = slower. Use another tool, ( eix,esearch ) they are better for |
32 |
this IMHO. Sorry it doesn't come all built into one tool, we are |
33 |
working on it. |
