Krcstat is a graphic replacement for the Gentoo rc-status and rc-update command line utilities. It can be used to check that all your services are active and generate an alert if they are not. You may easily create new runlevels and drag services from the Services pane into them. (Alternate runlevels may be specified by using the softlevel parameter on the kernel command line in Grub or Lilo.) Krcstat is a bit conservative and will not let you delete the boot or default runlevels or certain boot services deemed critical. To use its configuration features it must run as root; if you only want to monitor services, it can be run as a normal user.
mbrChunker is a utility that allows you to mount raw disk images (created by dd, dcfldd, dc3dd, ftk imager, etc.) and create VMDK files. It does this by taking the raw image, analyzing the master boot record (physical sector 0), and getting specific information that is need to create a working VMDK file that points to your raw image. It can also extract information such as heads, cylinders, and sectors per track. With version 0.3.15, the tool now has the ability to search for hex byte offsets within any binary file. It will give you the byte location for every hex pattern found. More information about this can be found in the README.
