** Description changed: - It appears that the latest version of coreutils uploaded to trusty- - updates has a regression in it. We have scripting that checks how much - space we have left on a partition using `df /dev/sda1`. Using coreutils - 8.21-1ubuntu5.1, we can do the following: + [Impact] + + * df fails to process devices that are specified on the command line. + + [Test Case] + + * Actual + $ df -h /dev/sda1 + Filesystem Size Used Avail Use% Mounted on + udev 1.8G 8.0K 1.8G 1% /dev + + * Expected + $ df -h /dev/sda1 + Filesystem Size Used Avail Use% Mounted on + /dev/sda1 9.9G 978M 8.5G 11% / + + [Regression Potential] + + * This patch is a partial backport of functions as they exist in vivid + to help minimize the regression potential. + + * That being said I had to do some backporting so as to avoid ui changes. + + * This once again significantly changes the mount search and matching + logic within df, but it is localized to df. + + [Other Info] + + * Anything else you think is useful to include + * Anticipate questions from users, SRU, +1 maintenance, security teams and the Technical Board + * and address these questions in advance + + + -------------------- Original Description----------------------- + It appears that the latest version of coreutils uploaded to trusty-updates has a regression in it. We have scripting that checks how much space we have left on a partition using `df /dev/sda1`. Using coreutils 8.21-1ubuntu5.1, we can do the following: $ df -h /dev/sda1 Filesystem Size Used Avail Use% Mounted on /dev/sda1 9.9G 978M 8.5G 11% / This is a valid way of using the tool per the manpage: "If an argument is the absolute file name of a disk device node containing a mounted file system, df shows the space available on that file system rather than on the file system containing the device node" It appears that either 8.21-1ubuntu5.2 or 8.21-1ubuntu5.3 broke this, however. We now get output for the udev filesystem that is mounted at /dev, instead of the device we pass in. - $ df -h /dev/sda1 + $ df -h /dev/sda1 Filesystem Size Used Avail Use% Mounted on udev 1.8G 8.0K 1.8G 1% /dev This is both a behaviour change, and contravenes the manpage, so it would be good to get this fixed.
