Re: [OT] Unrecognized mount option "uid=1000" error w/TrueCrypt 6.0a on Ubuntu 8.04.1 server x64



Hi Bob,

I'm grateful for your reply. Since I posted to Debian-users, I've had a reply to my second post on the TrueCrypt forum. That reply suggests that the error message is generated by a TrueCrypt assumption that the volume being mounted is formatted as FAT or NTFS, which mine isn't. Hopefully that means I can safely ignore the error message, although this goes against my instincts!

Nonetheless, I'll answer your points/questions below, in case this proves fruitful.

As noted on the Ubuntu forums page you reference, the TrueCrypt page
requires an account and login to view the details.

That's why I copied my post from the TrueCrypt forum to the Ubuntu forum, but not to worry.
 
I'm taking a blind shot (shot in the dark, whatever;) with this.

Does the 'uid=1000' follow the '-o' option?

Nope. My other posts at http://ubuntuforums.org/showthread.php?t=946994 will give you a better idea of what the error message looks like and the context in which it appears.
 
And, if it does, but there are other options used with it, is it a comma separated list?

No, I'm afraid not.
 
The pertinent part of the 'mount' man page is:

-o     Options are specified with a -o flag followed by a comma
      separated string of options.  Some of these options are only
      useful when they appear in the /etc/fstab file.

Interesting. Given that I didn't actually use the 'mount' command, I'm not sure this is relevant to me, but perhaps TrueCrypt is calling it. I haven't looked at TrueCrypt's source code to check this.
 
And many of the options are filesystem specific, so a final question:
Does the FS being mounted support the option?  The 'uid=...' is listed
under specific filesystem types, implying some don't support the
concept.

I was using the TrueCrypt command to mount an ext3 volume, which in fact doesn't seem to have 'uid=' listed as an option in the 'mount' man page.

All best,

Sam
