Re: MySQL and writing RAMFS for tmp question

Well, I must have been more precise. ramfs code explicitly prohibits user mounts, just like rootfs does. You can still try to run mysqld as root, but it does not make much sense and have ever been deprecated.

tmpfs does not use ramfs in anyway, so there is no point in "direct" ramfs usage though.

By the way, I use that size=700M tmpfs mount option to mostly avoid swapping. It is my workstation, I run Gnome desktop with all its niceties, so probably I have to go to the nearest retail shop to bye more RAM chips. The system locks up later, when the swap space is exhausted.

In the hope it helps.

Regards,
Vladimir
