Why Debian packaging structure is so difficult

[Sadhu Santh <sadhusanth001@gmail.com>]

Hi,

I am hosting a local Debian mirror for my LAN. This helps in low 
internet bandwidth use.

I keep only the required distributions (past five years and testing 
release).

Compared to other distributions such ArchLinux/RockyLinux (single line 
Rsync can do the job), the partial mirroring over Rsync in Debian is a 
complex process.

I use ftpsync, which can run on any Linux distribution.

Is there any simple set of Rsync commands to sync a particular version 
of the platform (e.g. x86) of Debian? If not, why the upstream structure 
is not made simpler?

Thanks for your guidance on the matter.


Regards,

SS
