findfs: unable to resolve 'LABEL="KDUMP TEST"'
Usage: mount -V                 : print version
       mount -h                 : print this help
       mount                    : list mounted filesystems
       mount -l                 : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
       mount -a [-t|-O] ...     : mount all stuff from /etc/fstab
       mount device             : mount device at the known place
       mount directory          : mount known device here
       mount -t type dev dir    : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
       mount --bind olddir newdir
or move a subtree:
       mount --move olddir newdir
One can change the type of mount containing the directory dir:
       mount --make-shared dir
       mount --make-slave dir
       mount --make-private dir
       mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
       mount --make-rshared dir
       mount --make-rslave dir
       mount --make-rprivate dir
       mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using  -L label  or by uuid, using  -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say  man 8 mount .

This is due to the double quote you put in kdump.conf, while the label itself doesn't contain any double quote. It's _not_ introduced by the original patch for this BZ.

Since it may block your testing, I will fix it now. My solution is:

+                config_val="$(echo $config_val | sed -e 's/"//g')"
                 config_val=$(findfs "$config_val")

However, this will cause problem if a label name really contains any double quote But that will be rare if not invalid.

Okay, I find another solution which seems better:

+                config_val=$(eval echo $config_val)

This will allow any valid single/double quotes in the label name in kdump.conf.

Verified with -87.el6.
