libblkid from e2fsprogs does not recognise vfat filesystem when formatted on Windows. In such case 'mount -t auto' won't work whereas 'mount -t vfat' will. Full description of the bug + patch is provided at given URL. Reproducible: Always Steps to Reproduce: 1.get pre-formatted USB storage 2.try to mount it mount it without '-t' option or '-t auto' 3. Actual Results: mount fails Expected Results: mount should work patch is confirmed to work on my amd64. I think 'emerge --info' is not necessary in this case, but if you really need it please let me know..
we need to know what version of e2fsprogs you're using
Forgot to mention - latest the greatest e2fsprogs-1.38 The patch provided on Redhat site is for 1.37 (didn't test it), but it worked fine with 1.38 as well (tested).
1.38-r1 should have this fixed
It seems that version 1.38-r1 does not fix the problem.. :-( If you need image of vfat filesystem (image provided on included URL is not available anymore) please let me know.. To fix the problem (actually to be able to mount filesystem) either I need to apply provided patch (look at URL) or compile util-linux with HAVE_BLKID=no in MCONFIG
Looks like problem has already been fixed in one of the recent releases. Closing bug.
