Space is not reserved for a tmpfs, it simply sets the maximum size to which the tmpfs may grow.
If a tmpfs is only using 5MB, then it will only consume 5MB of memory; it's backed by the page cache, so there is little overhead for such things as filesystem (in fact, there isn't one!) /dev is not writable by ordinary users, there is no danger of users filling this filesystem with other data. However there it is preferred that this filesystem "not become full", if the udev daemon is unable to make device nodes, or maintain its database, then system features such as hotplug fail to work and newly connected devices are not available. It is for this reason that we choose not to limit the size of the filesystem. status wontfix Scott -- Scott James Remnant [email protected] ** Changed in: udev (Ubuntu) Status: New => Won't Fix -- udev init script should use partition size from /etc/default/tmpfs https://bugs.launchpad.net/bugs/317161 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
