* migrate2rocky: use $convert_info_dir consistently
We set convert_info_dir=/root/convert. Use it consistently.
* migrate2rocky: avoid mkdir error with -rV options
Both -r and -V call `generate_rpm_info()` which run `mkdir` to create
the convert directory. The second call results in a warning:
mkdir: cannot create directory ‘/root/convert’: File exists
Use `mkdir -p` to avoid the spurious warning when the convert directory
exists.
* migrate2rocky: fix listing of rpm info files
When the conversion completes, the script prints:
You may review the following files:
However, there are no files displayed because the find pattern does not
match what `generate_rpm_info()` writes. It looks for '*-rpms-*' while
the files are named '*-rpm-list-*' instead.
Fix the file pattern used. While here, replace the use of `find` with a
simpler `printf` to achieve the same result.

|
|
Because CentOS Stream leads RockyLinux by the next point release many packages
|
|
in Stream will have higher version numbers than those in RockyLinux, some will
|
|
even be rebased to a new upstream version. Downgrading these packages to the
|
|
versions in RockyLinux carries the risk that the older version may not
|
|
recognize config files, data or other files generated by the newer version in
|
|
Stream.
|
|
|
|
To avoid issues with this the newer package versions from CentOS Stream have
|
|
been retained. Also the CentOS Stream repositories have been retained but
|
|
renamed with a prefix of "stream-" to avoid clashing with RockyLinux
|
|
repositories, but these same repos have also been disabled so that future
|
|
package installs will come from the stock RockyLinux repositories.
|
|
|
|
If you do nothing except update to the next point release of RockyLinux when it
|
|
becomes available then the packages retained from Stream should be replaced at
|
|
that time. If you need to update a package from Stream (eg: to fix a bug or
|
|
security issue) then you will need to enable the appropriate repository to do
|
|
so.
