What is strange is I create a directory under host:/dev/shm with these
uid:gid
picca@grades-01:~$ ls -l /dev/shm
total 172
drwx------ 2 picca grp-instrumentation 40 20 juin 14:46
dht-46013085715057
drwx------ 3 picca grp-instrumentation 80 20 juin 14:46
dht-46013101919192
But the version binmounted shows
root@sbuild:/sharedshm# ls -l
total 172
drwx------ 2 nobody nogroup 40 Jun 20 12:46 dht-46013085715057
drwx------ 3 nobody nogroup 80 Jun 20 12:46 dht-46013101919192
And if I try to list the content of one of these directory...
root@sbuild:/sharedshm# cd dht-46013101919192/
bash: cd: dht-46013101919192/: Permission denied
