@mia@movsw.0x0.st @icedquinn@blob.cat my bad, that was an unfinished thought. from the current dpkg-deb manpage, the utility that glues a package together:

```
-Zcompress-type
Specify which compression type to use when building a package.
Allowed values are gzip, xz (since dpkg 1.15.6), zstd (since
dpkg 1.19.0.5ubuntu2) and none (default is zstd).
```
they are cpio archives with any of the above compression, and the archive itself can ofc contain whatever pre-compressed files you desire.

in the Pentium II days, debian did skip over bzip2 for packages and it was due to the extreme memory requirements it demanded when the decision was made. anyone with less than ~64MB of RAM wouldn't have been able to install it, which would have excluded a huge chunk of hobbyists at the time.

by the time they got around to considering adding bzip2, xz had come along and was better in every way.

off topic, but, i'd like to see them add parallel decompression in dpkg-deb 👉👈
