Having a file that user.eclass would use to map new users/groups to |
| 22 |
IDs would be extremely beneficial to me. I was thinking about diving |
| 23 |
in to that some time later, after the GLEP 70 work I'm doing, but if |
| 24 |
someone else wants to take it - please! That would greatly ease the |
| 25 |
pain of not only NFS, but swapping data disks around between different / |
| 26 |
. |
| 27 |
|
| 28 |
Consider, for example, one of my use cases for this: I have a |
| 29 |
LibreSSL / that I use solely for testing ebuilds against it, and my |
| 30 |
regular / with OpenSSL. I share /home and /srv between these two, but |
| 31 |
the apache, nginx, and charybdis users have different UIDs between |
| 32 |
them. Therefore I have to chown -R each time I test LibreSSL. |
| 33 |
|
| 34 |
I could use a different /home and /srv, or make two copies, but it's |
| 35 |
much easier for me to test these apps having my entire normal |
| 36 |
environment available to me. |
| 37 |

Best, |
