I fully agree it needs a shortcut, and I would add that it needs |
| 12 |
more visibility in the docs. When you read forums, you realize |
| 13 |
that users almost never use this option when they should: each |
| 14 |
time somebody has a problem that can be solved by remerging a |
| 15 |
dependency (for instance a library, to add a USE flag or to bump |
| 16 |
it because a bug is solved), the answer other users give is |
| 17 |
"emerge libfoobar". And when I advice somebody to do an "emerge |
| 18 |
--oneshot something", I always get a "What is --oneshot, why |
| 19 |
should I use that here?". |
| 20 |
|
| 21 |
Sure, in an ideal world, users should never need to use this |
| 22 |
option. But because things are not always perfect, because |
| 23 |
packages sometimes have bugs and because portage has some |
| 24 |
limitations, the need to reemerge some libs happens from time to |
| 25 |
time. There are even some ebuilds that advice it in their einfo |
| 26 |
messages (maybe adding the command with --oneshot there would be |
| 27 |
a good start to teach users when to use it). |
| 28 |

I think the portage user guide needs a paragraph that would say, |
| 30 |
in short: |
| 31 |
-------- |
| 32 |
When you want to install a new package, use "emerge package". |
| 33 |
But when you want to re-emerge something that is already |
| 34 |
installed, for instance to update it or change its USE flags, use |
| 35 |
"emerge--oneshot package". You may want to define an alias for |
| 36 |
this to be sure you won't forget, in your ~/.bashrc: |
| 37 |
alias remerge='emerge --oneshot' |
| 38 |
-------- |
| 39 |
|
| 40 |
There also seems to be a confusion in users mind with the "-u" |
| 41 |
option. Many of them think that the way to update one, and only |
| 42 |
one, package is "emerge -u package" (whereas it is again "emerge |
| 43 |
--oneshot package"). I don't know exactly where it comes from |
| 44 |
(probably wrong assumptions based on the word "update"), but |
| 45 |
that's something I often read. |
