Also, does adding the option in a remount actually have any effect?

I tottaly agree with you It is for this reason that we choose not to limit the size of the filesystem. I think that you misunderstood me, I'm not suggesting to limit the size, I'm suggesting to allow people if they want, they can limit the size. Currently on ubuntu, I can do this on /dev/shm, /var/lock, /var/run, /lib/init/rw [1], but I can't on /dev The default behavior of my patch is to do nothing because the default contents of /etc/default/tmpfs on my ubuntu is to not limit size. So the patch only add support to allow people to choose the size, the patch is not imposing the size. IMHO I think that allowing people to choose the max size a good thing, but, anyway, the final decision is yours, and I will respect it.

[Bug 317161] [NEW] udev init script should use partition size from /etc/default/tmpfs
Public bug reported: I'm tunning ubuntu to a low memory device without swap (eee pc 701), I'm currently managing the max size of tmps partitions by setting size on /etc/default/tmpfs, but udev doens't use that settings, so I've made a patch to correct it. the default behavior to udev init script (kernel behavior) is to set tmpfs partition to half size of system ram that I think is too much, 8 MB would be sufficient using this patch, udev size will use UDEV_SIZE option if setted on /etc/default/tmpfs, if not setted it will use TMPFS_SIZE option if setted, and if not setted too, the default behavior is assumed this is my first patch, I don' t if I made it correctly following the guidelines ** Affects: udev (Ubuntu) Importance: Undecided Status: New -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
