Public bug reported: The version of 'mount' included in Ubuntu 14.04 LTS and 12.04 LTS has a bug wherein the 'exec' option in /etc/fstab is ignored on mounts with the 'user' or 'users' options when they are mounted by root. For example:
$ grep 48tb2d /etc/fstab labdisk.site.com:/Public4 /mnt/lab_48tb2d nfs users,exec,nosuid 0 0 $ sudo mount /mnt/lab_48tb2d $ mount | grep 48tb2d labdisk.site.com:/Public4 on /mnt/lab_48tb2d type nfs (rw,nosuid,nodev,noexec,addr=172.16.222.158) $ umount /mnt/lab_48tb2d $ mount /mnt/lab_48tb2d $ mount | grep 48tb2d labdisk.site.com:/Public4 on /mnt/lab_48tb2d type nfs (rw,nosuid,nodev,addr=172.16.222.158) This bug was fixed upstream several years ago and I believe therefore doesn't affect , but seems not to have made it into the current LTS releases of ubuntu. https://git.kernel.org/cgit/utils/util-linux/util-linux.git/commit/mount/mount.c?id=a4c0cc75ff9744299f108c259efab1bd30c8007a https://bugzilla.redhat.com/show_bug.cgi?id=769636 System info: Ubuntu 14.04.3 LTS, util-linux 2.20.1-5.1ubuntu20.7 ** Affects: util-linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1544251 Title: mount ignores exec option for 'users' mounts Status in util-linux package in Ubuntu: New Bug description: The version of 'mount' included in Ubuntu 14.04 LTS and 12.04 LTS has a bug wherein the 'exec' option in /etc/fstab is ignored on mounts with the 'user' or 'users' options when they are mounted by root.
