Description ghborrmann 2014-10-28 15:04:45 UTC

Description of problem:
When fatlabel is used to create a volume label on a fat system without one, it clobbers the first entry in the root directory

Version-Release number of selected component (if applicable):
3.0.26-1.fc20.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Use mkfs.fat to create a fat system on a file.  Do not specify a volume label.
2. Mount the file and copy a file to the new system.  I used a 9-character name to ensure that it would generate a long file name type of entry.
3. Unmount the file and label it using fatlabel.
4. Mount the file again and list the directory with ls
5. Unmount the file and run fsck.fat

Actual results:
In step 4, the listing gives the short file name (all caps, ending in ~1)
In step 5, fsck complains about a long file name overwritten by the short name.

Expected results:
ls should give the long file name; fsck.fat should give no errors.

Additional info:
Bug 1053158 appears to be related, but the above behavior is more serious.

If bug 1053158 is less severe, why is it embargoed when this bug isn't?

(And how come the message about the embargo when not even logged in is even less informative than the one shown when logged in with a baseline account?)
