RE: Unable to mount using credentials file

["Roger Brooks" <r.s.brooks-EkmVulN54Sk@public.gmane.org>]

Thanks for the tips, Steve!

My version of mount:
BusyBox v1.16.1 (2014-10-10 08:37:09 CST) multi-call binary.
does not appear to have a verbose option. At least:
mount --help
does not list any such option, and mount does not return any information to the console when it succeeds, regardless of whether or not I specify -v.

The failure message is also unchanged with the -v option:
mount: mounting //<IP address>/<share> on /mnt/<mountpoint> failed: Invalid argument

Also, I have read that mount maintains /etc/mtab.
Does that mean that mount will not list volumes which I mounted directly with mount.cifs, and that I cannot use umount to unmount volumes mounted directly with mount.cifs?

using /sbin/mount.cifs directly should be fine.   When you mount with
verbose mount option does it show any useful differences between the two cases (working vs. failing)
