I cannot reproduce this problem with the latest util-linux-ng: # strace -e mount mount -t vfat -o quiet /dev/loop0 /mnt/test mount("/dev/loop0", "/mnt/test", "vfat", MS_MGC_VAL, "quiet") = 0 # grep test /proc/mounts /dev/loop0 /mnt/test vfat rw,relatime,fmask=0022,dmask=0022,codepage=cp437,iocharset=ascii,shortname=mixed,quiet,errors=remount-ro 0 0 # uname -a Linux nb.net.home 2.6.34-11.fc14.x86_64 #1 SMP Sat May 22 01:03:52 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux Please, try to use: # strace -e mount mount -t vfat -o quiet <source> <target> or # mount -v -v -v -t vfat -o quiet <source> <target> to get more details.

I'm using *vanilla* 2.6.35 kernel.

Ah, I found the problem. The "quiet" mount option is translated to the MS_SILENT mount flags. Unfortunately, MS_SILENT is undefined in mount private header files (it still uses obsolete MS_VERBOSE). In your system the MS_SILENT macro is probably defined in /usr/include/sys/mount.h so the code that translate the "quiet" options is enabled. The another problem is that mount(8) uses the "quiet" for MS_SILENT mount flag and the same option (as string) is expected by vfat kernel driver... that's mess. I need to ask VFS hackers for more details. Anyway, thanks. Any updates on this bug? Six months and no updates. :( And the bug is still there. Sorry, for the delay. I'm going to resolve the problem ASAP. Fixed in upstream tree, commit 2ac1890aa0d8ce404528587134fcabe0e2834963. I'll add the bugfix to Fedora-15. This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
