When attempting to check if a package exists for a particular provide string what happened is if an older version of the package was on the system but a newer version in the repositories then the older (system) version would be returned by dnf provides, but this could not be translated into a package name with dnf repoquery because that specific version could not be found in the repos. The solution was to check rpm first to translate the package name on the system and then dnf repoquery if rpm doesn't find it. This brought to light issues when passing arrays of package names to rpm and dnf which might happen to contain an empty element. In this case rpm and dnf would consider the empty arg an indicator that it should match all packages on the system, or all available packages. While we should try to avoid passing arrays with empty elements, this highlighed a need to make rpm and dnf safer in this regard, and so there are now saferpm and sfednf functions which simply strip any empty args before calling the appropriate command with the rest of the args untouched. This commit also fixes an issue with output column formatting. |

Rocky Tools
Various scripts and tools that we find useful, whether we use them or they are made for public consumption. For example, conversion scripts or otherwise.
[migrate2rocky] -- Conversion Script
Running this script will convert an existing CentOS 8 system to Rocky Linux 8.
Usage
./migrate2rocky.sh -h
├── -h # --> Display this help
├── -r # --> Convert to Rocky
└── -V # --> Verify switch
[!! USE WITH CAUTION !!]
Known Issues
RHEL migrations show error messages during conversion
Installing : rocky-release-8.3-13.el8.noarch 2/5Error unpacking rpm package rocky-release-8.3-13.el8.noarch
...
error: unpacking of archive failed on file /usr/share/redhat-release: cpio: File from package already exists as a directory in system
error: rocky-release-8.3-13.el8.noarch: install failed
...
Error: Transaction failed
This results from conflicts in the directory structure of RHEL with that of RockyLinux. migrate2rocky will detect the issue and go on to remove the conflicting directory and install rocky-release with the rpm command.
Grub still shows kernel entries from previous installation
This is normal. The running kernel cannot be safely removed when migrate2rocky is run. The RockyLinux kernel should come up as the default highlighed kernel on reboot but the other ones will remain until they are removed or replaced by newer kernels. If you want you can manually remove the old kernels after reboot with dnf or rpm.
Latest Version
The latest version of this script can be found here.
