Dear fellow mages,
Bug #16011 [0], recently filled, deals with the issue of upgrading
an old system to the latest stable releases.
Since a while ago, some of the sources of spells in stable are
compressed by xz, but this format is not recognized by older versions
of the `file` command, which sorcery uses to figure out how to
decompress the file.
As a first measure to avoid this issue now and in future releases, I
would like to replace the code dealing with parsing the output of the
`file` command with a custom script that detects only the formats
needed by sorcery, and has no external dependencies. A prototype
written using only dd and awk is attached to the bug report [1].
I would like to hear opinions about this implementation and any ideas
about how it could be improved.
Regards.
