Hi -
Is yum-presto known to work on arm? Today I changed our repo to use
deltarpms and tested it out. I noticed...
1) On a package where I know the bulk of the unpacked data is some fonts
inside an ELF executable that didn't change, the compression result
was... not good
Old RPM: 25424385 txtr-reader-0.1-417.fc11.armv5tel.rpm
New RPM: 25465487 txtr-reader-0.1-420.fc11.armv5tel.rpm
Delta RPM: 25465402 txtr-reader-0.1-417.fc11_0.1-420.fc11.armv5tel.drpm
So it saved me 85 bytes from 25MByte :-)
The actual procedure here is the createrepo is run on an x86_64 box over
these arm packages and then rsync'd on a server.
2) Using deltarpms fails

Any advice welcomed, it would be great to reduce this 25MByte package
down since the vast bulk of it is exactly the same each time :-)

If you can get me ssh access to an arm machine, I'll look into both of
these problems. Please also open a bug against deltarpm (otherwise, I'll
totally forget about this).
