I like to label my grub boot options with the correct kernel version/build.

After building and installing a new kernel with "make install" I had to edit my grub.conf by hand.

To avoid this, I've decided to write this little command line to:

1. read the version/build part of the filename to which the kernel symlinks point

2. replace the first label lines of grub.conf

grub.conf label lines must be in this format:

Latest [{name}-{version/build}]

Old [{name}-{version/build}]

only the {version/build} part is substituted.

For instance:

title Latest [GNU/Linux-2.6.31-gentoo-r10.201003]

would turn to

title Latest [GNU/Linux-2.6.32-gentoo-r7.201004]"
