# Project IDs on systemd Systems
|
|
|
|
Project IDs are needed to enforce disk quotas for Exec Directories.
|
|
Project IDs are unsigned, 32-bit integers. For disk quota enforcement,
|
|
the range used is 2147483648 - 4294967294, which is the highest range
|
|
inspired from `UIDS-GUID.md`. The range is defined through `PROJ_ID_MIN`
|
|
and `PROJ_ID_MAX` in `exec-invoke.c`.
