Extraneous tmpfs mounts of /tmp and /media/ram in fstab

[mwester@…]

The /etc/fstab file explicitly mounts /tmp as well as /media/ram as filesystems
of type tmpfs. This conflicts with the configuration of the "volatiles"
mechanism which redirects (among others) /tmp to be a symbolic link into
/var/volatile (which is a tmpfs filesystem). (This also results in an error
message printed at boot time -- "Device or resource busy" -- and a strange entry

symbolic link from /tmp/tmp->/var/tmp).

Additionally, there is no need for /media/ram to be mounted as a tmpfs
filesystem, as applications and users should use a directory in /var/volatiles
instead.

The solution is to remove the lines for /tmp and /media/ram from the fstab.

[Note that as an alternative, if it is deemed desirable that we have two tmpfs
mounts for temporary data, then the /etc/default/volatiles configuration should
be adjusted to remove the reference to /tmp.]

Is this fixed in OE now?

[mwester@…]

No, as of 28 Oct 2007 no fix has been committed to OE.

[john_lee@…]

I'll take a look into it.

Thanks for Mike's detailed description. Fixed in OE on monotone.openmoko.org .
