Problem with --bind mounts when /etc/mtab is a symlink to /proc/mounts
Last modified: 2007-11-16 20:15:00 EST
Description of problem: When /etc/mtab is a symbolik link to /proc/mounts, the following problem occurs: mount -a will mount entries in /etc/fstab with bind options several times. Version-Release number of selected component (if applicable): util-linux-2.13-0.45.el5 How reproducible: Always Steps to Reproduce: 1. create /etc/mtab as a symlink to /proc/mounts 2. create a fstab entry with bind option: /mnt/test/source /mnt/test/dest none bind 0 0 3. exec mount -a twice 4. read mount information Actual results: after executing mount -a twice, mount shows: /dev/root on /mnt/test/dest type ext3 (rw,data=ordered) /dev/root on /mnt/test/dest type ext3 (rw,data=ordered) Expected results: after executing mount -a twice, mount should only show /dev/root on /mnt/test/dest type ext3 (rw,data=ordered) once. Additional info:
The symlink to /proc/mounts is non-standard and **unsupported** change (yet). It's source for many problems. The /proc/mounts doesn't contains all relevant information.
