I can use mash to get all packages from koji with "mash dist-fc13"
When i have a new build , i don'tÂ* want to reget all packages form koji , i just want to get the package like update .
can mash do that?

How to use mash to get update packages?

How to use these options below ,and What is their purpose？

Â* -p PREVIOUS, --previous=PREVIOUS

Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â* previous mash run to use as basis for createrepo
Â* -d DELTA, --delta=DELTA
Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â* previous directory to use for deltarpm creation

I can't find docs for mash, ^-^


Thanks

Sure. Given that updates go to dist-f13-updates-candidate, etc., you
probably want to be using that.

This directory specifies where it copies prior metadata from, to speed
up metadata creation.

This specifies what mash creates deltas against. (It defaults to whatever
you set '-p' to.)

What are you trying to use mash for, in general? It's sort of a
special-purpose tool.

Thanks for your reply.

but i don't understand the "delta" too, and how to use this option ,Â* is itÂ* "mash -d dist-fc13"Â* ?

I am building my own distribution, so i use koji to build srpms.

and then i want to extract pkgs from koji with mash.

but when i use "mash xxx ", it will delete old mash dir and get all pkgs then createrepo again.
when i have some new builds in koji ,i only want to extract these new pkgs to the old repo, not redo mash again.

It will waste too much time.

It's for creating deltarpms. If you don't know what those are,
don't worry about it.

Right, that's the intention. It does create/use a cache in
/var/cache/mash, assuming that's writable by the mashing user.

As I said, it's intentional that it creates a new repo each time; you can't
change this. You can use the caching feature to cut down on bandwidth use.
