xf86-video-intel-20200218 (and others) file format

[thomas]

The download file is named xf86-video-intel-20200218.tar.xz

but it is a bzip2-compressed file:

$ file /mnt/LFS/conglomeration/xf86-video-intel-20200218.tar.xz
/mnt/LFS/conglomeration/xf86-video-intel-20200218.tar.xz: bzip2 compressed data, block size = 900k

So, either name of compression-type is not what it should be.

It does not harm if "tar -xf <tarball>" is used. That might be the reason why it hasn't came up so far. But it breaks if doing "tar -xJf <tarball>". The capital 'J' is what the extension of .xz suggests.

That breaks scripts which are using the file naming to prepare options for the tar command. Regardless if that approach (using "extensions" for controlling script functionality) is good or not, we should not mix extensions/file-formats.

Same for cairo-1.17.2+f93fc72c03e.tar.xz

$ file /mnt/LFS/conglomeration/cairo-1.17.2+f93fc72c03e.tar.xz
/mnt/LFS/conglomeration/cairo-1.17.2+f93fc72c03e.tar.xz: bzip2 compressed data, block size = 900k}}}
