/var/shared_memory not created at startup

[saprykin]

According to source code /var/shared_memory directory is being used for shared memory handles. In the latest nightly build hrev50290 that directory not created and shm_open() fails. In the stable release R1.A4 there is no such a problem. After creating /var/shared_memory manually shm_open() works fine.

The former Bootscript had the following, before anything else was started:

# clean the shared memory dir
shmDir=/var/shared_memory
rm -rf $shmDir
mkdir -p $shmDir
chmod 777 $shmDir

Maybe this could be done directly by the launch_daemon, also before anything else.

The launch_daemon is already supposed to do that directly, see ​http://cgit.haiku-os.org/haiku/tree/src/servers/launch/InitSharedMemoryDirectoryJob.cpp - it's also added to the system init jobs (​http://cgit.haiku-os.org/haiku/tree/src/servers/launch/LaunchDaemon.cpp#n1850) - so if that doesn't work anymore, there is something very wrong.

[korli]

Given that /var is a symlink, maybe create_directory () doesn't handle this correctly?

Fixed in hrev51089.
