The "fmconv" script modifies the /etc/fstab file and the /boot/grub/menu.lst file to use either UUID strings or device filenames depending upon the parameter settings (-u or -d). This easy conversion to device filenames for maintenance purposes (UUID strings are hard to maintain, and just annoying), and the conversion back to UUID strings allows grub to work in an environment where the boot disk sequence is poorly defined by the BIOS. The original files are never overwritten.
mod-icon-geom is a command line utility that allows the user to set the KDE 4 desktop icon's height and width. It creates a configuration file by using the -c option along with default height (-h) and default width (-w) option settings. It modifies the geometry for each desktop icon found in .kde4/share/config/plasma-desktop-appletsrc to make the icons have the desired height and width. After the configuration file is generated, the user can modify that file to have height and width values for individual icons that are different than the default (useful if the icon text is larger than the default width allows), and the true values in the appletsrc file can be saved back to the configuration file with the -s option. This utility saves time and energy by giving the user an additional level of control over desktop icons that was lost in KDe 4.
