6 | # Simple script to generate a deb package for a Linux kernel. All the | |
4f66199b | 7 | # complexity of what to do with a kernel after it is installed or removed |
1da177e4 | 8 | # is left to other scripts and packages: they can install scripts in the |
fe233cb6 FP |
9 | # /etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location |
10 | # specified in KDEB_HOOKDIR) that will be called on package install and | |
11 | # removal. | |

159 | Description: User Mode Linux kernel, version $version | |
160 | User-mode Linux is a port of the Linux kernel to its own system call | |
161 | interface. It provides a kind of virtual machine, which runs Linux | |
162 | as a user process under another Linux kernel. This is useful for | |
163 | kernel development, sandboxes, jails, experimentation, and | |
164 | many other things. | |
165 | . | |
166 | This package contains the Linux kernel, modules and corresponding other | |
a83ca277 | 167 | files, version: $version. |
