# List of AL2027 reserved groups
<a name="reserved-groups"></a>

**AL2027 Preview**  
AL2027 is currently available for preview. It is intended for evaluation and testing only and is not recommended for production workloads.

The following tables list the group names that AL2027 packages reserve, as of the AL2027 public preview. A numeric GID is listed when the group is created with a static GID. A group marked *dynamic* is allocated a GID from the system range (201-999) when the owning package is installed, so the number varies between instances. The list grows as packages are added to AL2027.
