[Kolab-devel] [PATCH 2/2] Check if /dev/shm is mounted (Linux only)

[Jeroen van Meeuwen (Kolab Systems)]

Hi Franceso,

I'm very sorry to get back to this only as late as I do now... My 
apologies. Thank you for the patch!

I would consider, that often the issue is that, while /dev/shm might be 
mounted, it might still not be mounted read-write.

That said, however, I'm uncertain whether an additional test for 
os.access('/dev/shm/', os.W_OK) would be appropriate, as I myself run no 
LXC/OpenVZ type of "virtual but not actually virtual" virtualization.

If you could help me understand what this actually means / would 
actually do, I'd be more than happy to accept the patch and/or make the 
additional adjustments.
