Ubuntu 12.10 (Quantal Quetzal) on Fujitsu LIFEBOOK UH572

When I became a LIFEBOOK4LIFE insider, the first thing I had in mind was to install a Linux distribution on the device. The UltrabookTM came with Windows7 installed on. Frankly I do not fancy it (though I must admit it is a relief after Windows Vista), as I live on Linux almost all the time. (more…)

How to force a fsck after reboot?

For various reasons you may want to force a check (fsck) of a filesystem you currently use (most likely the root / filesystem as you cannot umount it on-the-go). To achieve that do: (below is for the / mount)

    # touch /forcefsck

and after the reboot you’ll see that the fsck is being done.

Fedora 12 / boot / initrd / initramfs

I have been using Fedora 12 (under HVM – Oracle VM 2.2) to build latest
kernels from git (kernel.org), identify bugs, bisect, build and test.

On Xen HVM Fedora 12 is quite slow (a full kernel build takes 3.5
hrs). I have noticed
that initrd / mkinitrd does not have a future as Fedora 12 uses dracut
to create initramfs (and initramfs – not initrd – check this nice blog entry).

The
initramfs initially was 60 GB and it took ages for the guest to boot up
.. Unbearable! .. With the idea by jch to remove plymouth
(graphical boot) from initramfs – by telling dracut not to include it I
added the following to /etc/dracut.conf file:
   omit_dracutmodules=”plymouth”
That made my initramfs file of 45MB size – which is still big but at least bootup takes shorter time. Now I can bisect happily 🙂
