[Bug 451748] [NEW] unused filesystem modules are loaded

[Sergei Ivanov]

Public bug reported:

Binary package hint: initramfs-tools

After booting current kubuntu karmik beta, lsmod shows the following:

I have only ntfs, ext3 and ext4 filesystems on this machine, and only
ext4 is mounted. The rest of the above modules just sits there and eats
the non-swappable kernel memory. I'm sure they contribute to boot time
as well. And who knows whether the code from these modules is running or
not.

I expect that modules for non-existing stuff are not loaded, and this
was the case in Ubuntu 8.04 (I did not check anything in between).
However cheap the memory is these days, I still think that the issue is
worth fixing.

I'm not sure that it is the initramfs-tools package that is responsible
for this, but anyway its version is 0.92bubuntu53.
