Jan 31, 2015 7:44 PM in response to mknjby jturquette,Hello mknj,
I am also attempting create a bootable usb flash drive with the yosemite installer. I have not had this error. Is it possible that the installer does not like the untitled name for the volume? after typing in my password, the computer terminal returned with:
To continue we need to erase the disk at /Volumes/Recovery.
If you wish to continue type (Y) then press return:
the name I made for the flash drive was recovery.
So far so good. I will let you know if I am successful...

Oct 17, 2015 4:07 PM in response to jturquetteby neatlyfolded,I had the same problem as OP. The process that jturquette used / posted here worked for me.\
Note: I was trying to create a bootable Yosemite install drive, destination being a USB thumb, working in 10.10.5. I followed Apple support page's directions for drive formatting and 'create install media' operations. I received the same 'invalid volume mount-point' message in Terminal. This occurred multiple times and seemingly regardless of drive name or mounting. When I changed my destination volume name to "Recovery", as jturquette described, the remainder of the Apple-specified process worked.
Mac Pro 3,1
PNY 68GB USB3 FD
OS 10.10.5

Oct 21, 2015 3:46 AM in response to mknjby Subodh_IT,try this

Jan 15, 2016 7:22 PM in response to mknjby Ads430,I had the same issue. It turns out the external drive needed to be named untitled with a lower case "u" at the start even though the sudo command I cut and pasted had Untitled with a capital U.
Here is the sudo command I used:
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction
After I renamed the external drive to untitled it worked straight away.
