severity 359717 important thanks Hi all, while checking hylafax bugs #551566 and #551443, I found a problem with mountpoint command. Browsing initscripts bugs, it seems this is already reported as #359717.
I checked mountpoint source code and found that it does an stats() of the supposed mount point and its parent directory. If both stats() report the same block device, then mountpoint think this is not a mount point, otherwise it says it is a mount point. So, if a system has its root file system mounted from device /dev/sda1, and a second mount point is created with "bind" option, i.e., without having an underneath block device, then, when mountpoint is invoked, it does not find the correct nature of second mount point. For fixing this bug I wonder if it possible to scan /etc/mtab and identify all possibile mount points. An alternative could be use /proc/mounts, but I suppose this is not always available since probably it is Linux related and won't work on *bsd or hurd kernels. Of course, current behaviour could be left unchanged for systems where no /etc/mtab is present. As a side note, hurd might use /etc/mtab, as I found here: http://www.gnu.org/software/hurd/community/gsoc/project_ideas/mtab.html Bye, Giuseppe -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
