Description Manuel Mommertz 2020-05-04 07:26:05 UTC 
According to [1] the range of dynamic uids and gids is 500..999.

But /etc/login.def does not implement this range:

$ grep 'SYS_[GU]ID' /etc/login.defs 
SYS_UID_MIN               101
SYS_UID_MAX               999
SYS_GID_MIN               101
SYS_GID_MAX               999

SYS_[GU]ID_MIN should be set to 500 to prevent dynamic ids to block fixed ids of other groups

Reproducible: Always

Which is fine, we allocate free [GU]IDS in the descending order.
