Hi
I have just had to hand roll my SUSE kernel, and somewhere along the line I switched off
SUBFS. (I get this message on booting up: mount: fs type subfs not supported by kernel)

The crazy thing is, I just can't find which .config line it is to switch it back on again. I've googled half the day and can't see anything either.

Anyone know which option it is - it's certainly not obvious from the documentation.

Tks

maybe I'm wrong but isn't that something to do with the ability to mount floppies, CD and the like automatically? There's probably an entry for this somewhere in the .config file.

Indeed ...but what is it? It ain't obvious

You can find info on subfs at the following URL:

http://submount.sourceforge.net/

Download the latest sourcecode for submount. As the rpm only works for a stock kernel you will have to compile the module seperately from the kernel. The instructions are in the INSTALL file.

Works like a champ on my Suse 9.1 system.

I've been struggling for a bit with this one. Baffled me entirely until, partially, I read the SuSE 9.1 release notes. Submount, as mentioned in this thread, is included as standard in SuSE 9.1.

SuSE haven't, however, included it in the kernel section, you'll need to go to /usr/src/kernel-modules/subfs directory. Apparently all you need to do is run "make" and then "make install" and it'll add it into the kernel modules for you *shrug*

We'll see.. I'll be handrolling another kernel at some stage and I guess I'll have to wait and see what happens.

Thanks - this has been unresolved for a while.

I have a similiar problem!i've opened up a thread here : http://www.linuxquestions.org/questi...subfs+suse+9.1
But i have a problem. I've make and make install (as su) as mentioned above but when i modprobe subfs i get this

linux:~ # modprobe subfs
FATAL: Error inserting subfs (/lib/modules/2.6.4-52-default/extra/subfs.ko): Invalid module format

What can i do?

Anyone?

mmmm - dunno.

But, I've seen that error when one tries to insert a module into a different kernel version to the runing kernel.

I notice that you are running *52* - silly question, but if you have been running the online update, you will be using a newer version - are you sure that the module you are compliling is for the correct
version?

Just to be sure, you maybe remake all you modules (first delete the /lib/modules/kernel ver).

I.e make modules and make modules_install, then to the make subfs thing.

L

Should i just delete the folder , and then cd /usr/src/linux , make modules then make modules_install and finally do the make subfs thing? No make install etc etc for the kernel?

yep..delete lib/modules/2.6x

Then just do the make modules and make modules_install.

If it does not work, do the kernel bit too. Remember, this is just a chancer - I'm not totally sure that this will sort out the problem

I'll try it both ways and post results! Thanx anyway lacerto!

I've ended having to try this myself, but don't have /usr/src/kernel-modules directory.

I've got the kernel sources, but but not that one? any idea

the sources are in a separate package called km_submount.

Hi - got this to work in the end, but had to do it slightly different.

I did:
make modules (note: not make)
make install
depmod -ae
