[solved] Extracting initramfs / initrd img fails with message "gzip: /boot/initramfs-*.img: not in gzip format"

when trying to extract initramfs using the old method (gzip) in fedora 19 (f19), fails with the following error message.

# cd `mktemp -d` && gzip -dc /boot/initramfs-fedup.img | cpio -ivd

gzip: /boot/initramfs-fedup.img: not in gzip format
cpio: premature end of archive

This is because in f19, initramfs format has been changed from gz to xz.

# file /boot/initramfs-fedup.img
/boot/initramfs-fedup.img: XZ compressed data

The solution:

cd `mktemp -d` && xz -dc /boot/initramfs-fedup.img | cpio -ivd

Change gz to xz .. :)

How to fix the missing system tray icons in Fedora 15 (F15) Gnome3

When starting applications such as parcellite, dropbox which needs a system tray, their icons are missing from Gnome3 system tray. The issue is caused due to a bug in Gnome3 and is fixed in the latest update.

# yum update gnome*

Once the update is finished logout ( a reboot is recommended ) and login again.

Still you cannot see the icons in system tray??

Make sure you are checking at the right place. In Gnome3 the system tray is not at the top right hand corner. It is visible at the bottom right hand corner of the activities (alt + f1) screen.

See the screen shot below,
