[kde-freebsd] Free-BSD large FAT-Partitions with HAL in 6.3 and 7.0

[peter weismann]

Since kernel option MSDOSFS_LARGE is no longer available in Free-BSD 
6.3 and 7.0 automatic mount through HALD (in my case on USB- 
changeable media) is not working anymore.

I had this small conversation below with Joe Marcus Clarke 
<marcus at freebsd.org>, who stated to add the mount_msdosfs option -o 
large in HAL, but I did that already and it did not work in KDE. 
Joe mentioned, that KDE must have a volume manager, that must be 
taught what mount options are needed, like gnome would have. 
I am low level Unix-User.
As far as I understand this, KIO and KIOSLAVE take care for this 
subject in KDE, but I did not see any chance to configure and allow 
the mount with the option -o large, that HAL now sends.

I hope you can understand what I mean and am looking forward for some 
help.

Okay, I'll add the new option.

I'm not a KDE user, so you'd have to ask the FreeBSD KDE people.  
There
must be some way of telling KDE to use the new option once HAL becomes
aware of it.

The Fuse change looks to be non-trivial, and I did not want to break
existing (working) NTFS support.  I would be happy to implement NTFS
read-write through fuse, but I need some basis for getting this 
working
in FreeBSD given the way our mount works.  That's why I was hoping 
some
fuse users would contribute.
