<p>The current handling of users and groups in the portage system lacks
|
| 334 |
|
|
policy and a decent API. We need an API that is both simple for
|
| 335 |
g2boojum |
1.1 |
developers and end users.</p>

|
| 339 |
|
|
<p>Currently the policy is left up to respective ebuild maintainers to
|
| 340 |
|
|
choose the username, id, shell settings, etc... and to have them added
|
| 341 |
|
|
in the right place at the right time in the right way. When the
|
| 342 |
|
|
addition of users was found to often times have broken logic, the
|
| 343 |
|
|
enewuser and enewgroup functions were designed to remove all the
|
| 344 |
|
|
details. However, these functions still suffer from some fundamental
|
| 345 |
|
|
problems. First, there is no local customization. Second, maintainers
|
| 346 |
|
|
still use the functions improperly (binary packages have suffered the
|
| 347 |
|
|
most thus far). Third, the functions are not portable across non-linux
|
| 348 |
|
|
systems and not friendly to cross compiling or other exotic setups.
|
| 349 |
|
|
There are other reasons, but these listed few are enough to warrant
|
| 350 |
g2boojum |

change.</p>

<p>New directories will need to be added to the rsync tree to store the files

that define the default values for new accounts. They will be stored on a

|
| 361 |
|
|
The default location will be the base profile since all other profiles inherit

from there.</p>

<p>The files are named with the respective user/group name since they need
|
| 370 |
|
|
to be unique in their respective domains. For example, the file
|
| 371 |
|
|
detailing the ntp user would be located accounts/user/ntp. Each
|
| 372 |
|
|
username file will detail the required information about each user.
|
| 373 |
|
|
Certain account features that exist on one class of systems (Linux) but
|
| 374 |
|
|
not on others (*BSD) can be redefined in their respective subprofiles. Each
|
| 375 |
|
|
groupname will follow similar guidelines. The accounts file will be used to
|
| 376 |
|
|
describe global account defaults such as the default range of 'valid system'
|
| 377 |
|
|
ids. For example, if the UID 123 is already used on a system, but the ntp
|
| 378 |
|
|
user defaults to '123', we obviously cannot just duplicate it. So we
|
| 379 |
|
|
would select the next available UID on the system based upon the range

easily override the defaults Gentoo has before dictated. The default
