Subject: [PATCH] Increase NGROUPS_MAX from 32 to 1024
 
Such a restrictive value for NGROUPS_MAX makes it = impossible to have a musl-based system with a user belonging to more than 3= 2 groups. If done on the root user, this will break your system.
It also makes it impossible to use certain functions in binaries that have = been compiled with musl.

This new value is still very far from Linux's NGROUPS_MAX of 65536 that has= been there since Linux 2.6.4 but this is at least one tiny step in the rig= ht direction while maintainers investigate how to match Linux's value.
