[gentoo-user] /usr/portage/packages/Packages - what for?

2009-09-15 Thread Helmut Jarausch 
Hi,

I have the impression that when rsync'ing /usr/portage/packages from
another machine (BINSERVER), 
emerge --update --newuse --deep --buildpkg @system @world
doesn't update packages which are upto-date on BINSERVER
but not upto-date on the local machine.

What's the role of the file
/usr/portage/packages/Packages

Many thanks for a hint,
Helmut.

Here it stores alotta info about the binary packages - for instance with what 
useflags they were compiled. This info is not in the archives, which only 
contain the files.

No, informations about environment are included in tbz2 packages.
You can read man xpak for explanations.

IMHO, the /usr/portage/packages/Packages file is an index for the
package manager to avoid wasting time to open, parse and close each
tbz2 file.

Does emaint --fix binhost help?

Many thanks, that looks great.
I'll test it next time.

And it's fetched by machines using a BINHOST, as obviously over HTTP it's not 
practical to fetch the packages themselves to get the environment info.
