I spent yesterday trying, unsuccessfully, to modify the kernel, removing modules that I don’t need. In this case, the modules are the Cram, Reiser, and Squash filesystems.
The following command lists the modules in the kernel:
lsmod
To get the filesystem modules,
lsmod | egrep “fs.ko$” | less
To remove a module, either the rmmod or modprobe commands can be used. Modprobe is preferred. This intelligently adds or removes modules.
The command I used was:
sudo modprobe -v -n -r cramfs reiserfs squashfs
-v –verbose
-n –dry-run
-r –remove
The verbose option should tell me what’s happening, error or not, but the above command executed with no error, or feedback of any kind.
modprobe expects an up-to-date modules.dep file, as generated by depmod. I looked for and found modules.dep, so I am still stumped on this one.
