Hi,
is there any reason why SHM must be mounted on /var/shm? If I have
mounted it in /shmfs, it does following (with xawtv):
strace:
shmget(IPC_PRIVATE, 221184, IPC_CREAT|0x1ff|0666) = 65538
shmat(65538, 0, 0) = -1 EINAL
ipcs:
key shmid owner perms bytes nattach status
0x00000000 65538 root 777 221184 0
ls -la /shmfs (except strange empty entry):
-rwxrwxrwx 1 root root 221184 Mar 13 12:19 .IPC_00010002
When I mounted it in /var/shm, it works. Could not shm code start
walking tree in shmfs root instead of in real root on path /var/shm?
Have I different SHM namespace if I mount shm in chrooted environment?
Unfortunately, I do not have address of author of shm changes, so
I'm asking here.
Thanks,
Petr Vandrovec
