I'd like to take back my earlier comment. It all starts in https://bugs.debian.org/cgi- bin/bugreport.cgi?bug=653073
In 14.04.3, the final straw for me is the transition from coreutils 8.21-1ubuntu5.2 to coreutils 8.21-1ubuntu5.3. In my case, there is an enabling requirement: grub must pass root=UUID =<uuid-string> to the kernel at boot time. I can restore the "correct" output from `df /` if I first uncomment GRUB_DISABLE_LINUX_UUID=true in `/etc/default/grub`, followed by running `update-grub`, and reboot. This type of change may not work for everyone, as some folks may be relying on UUIDs for consistent volume identification. Ymmv. It would be nice if `df /` could run `readlink -f` on the filesystem in column one, perhaps as a flag or ENV variable, but that's a separate story. ** Bug watch added: Debian Bug tracker #653073 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=653073 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to coreutils in Ubuntu. https://bugs.launchpad.net/bugs/1527416 Title: Unexpected change in "df /"output Status in coreutils package in Ubuntu: Confirmed Bug description: An unexpected change in the output of "df /" has happened in either coreutils 8.21-1ubuntu5.3 or 8.21-1ubuntu5.2. After doing updates on a number of servers today, the output of "df /" has changed. It now shows the full device path, including uuid of the device, instead of just the "generic" device. For example, on an updated server with coreutils 8.21-1ubuntu5.3: # df / Filesystem 1K-blocks Used Available Use% Mounted on /dev/disk/by-uuid/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx 8115168 3542936 4136956 47% / On a server with coreutils 8.21-1ubuntu5.1: # df / Filesystem 1K-blocks Used Available Use% Mounted on /dev/xvda1 8115168 4260144 3419748 56% / This makes scripts or other processes (monitoring scripts to report available disk space, for example) that rely on a standard filesystem name across numerous servers break, as each server will have a different disk UUID. Oddly, attached volumes (non-root volumes) don't exhibit the behaviour, and continue to show the "generic" device: # df /media/ebs1 Filesystem 1K-blocks Used Available Use% Mounted on /dev/xvdf 104806400 43260 104763140 1% /media/ebs1 # lsb_release -rd Description: Ubuntu 14.04.3 LTS Release: 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/1527416/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
