A bit of background: |
| 2 |
|
| 3 |
nix and guix are both hermetic builders with precise dependency |
| 4 |
management: all build inputs are explicit and build outputs should |
| 5 |
ideally not change if build inputs don't change. |
| 6 |
|
| 7 |
Every user in the system can trigger the build via IPC request |
| 8 |
to the builder daemon (nix-daemon or guix-daemon). |
| 9 |
|
| 10 |
For each IPC request builder daemon pick free user from user pool |
| 11 |
dedicated specifically for building. In case of nix pool group |
| 12 |
is 'nixbld' and users in that pool are 'nixbld1', 'nixbld2', and so |
| 13 |
on. There is no fixed limit on a pool size. Nixos creates 32 users: |
| 14 |
nixbld{1..32}. |
| 15 |
|
| 16 |
That way different users can't interfere with one anothers' build. |
| 17 |
|
| 18 |
Groups/users have a few properties: |
| 19 |
- final build results are owned by root:root and never by |
| 20 |
nixbld{1..10} users |
| 21 |
- nixbld{1..10} own only temporary build directory while IPC |
| 22 |
request is handled. Temporary directory is deleted when build |
| 23 |
is finished. |
| 24 |
- the more concurrent clients are there the more users should |
| 25 |
be in the builder group. |
| 26 |
|
| 27 |
There is a GID collision: |
| 28 |
Both nix and guix use GID=30000 for their 'nixbld' |
| 29 |
and 'guixbuild' groups. As Gentoo allows both to co-exist |
| 30 |
one of them has to give. I've moved guix down to 31000. |
| 31 |
|
| 32 |
I've effectively reserved space for 1000 users for each of them: |
| 33 |
- 30000..30999 |
| 34 |
- 31000..31000 |
| 35 |
and using only 10 of each. |
