Hi, I have found the old thread[1] about SHM Linux emulation and have them issues to get it to work inside a jail. I fail to create a /dev/shm directory for the devfs inside the jail. I added the 'link /tmp shm' to the /etc/devs.conf, I edited /etc/defaults/devfs.rules to attempt to unhide shm and 'shm/*' but the 'shm/' directory does not become visible inside the jail. any idea how to get this to work in a Jail? holger PS: I looked at both GLIBC ntpl/sem_open.c and linux_stats.c. One option would be to list another directory in /proc/mounts with tmpfs/shmfs and replicate the check in linux_stats.c for this alternative directory.
