Basically it's a lot harder to support than you think it is and any voodoo patch you might come up with to support it in portage is very unlikely to be accepted. ROOT is the closest thing that is supported and unlike altering prefix in the ebuilds or setting EXTRA_ECONF=--prefix=/blah it actually works for packages that don't use autotools properly. As detailed in `man make.conf` all build time dependencies of packages that are installed in a ROOT different from / will need to be installed in / (automatically by portage) so it's far from ideal for this purpose. Changing --prefix is much more ideal either as it won't magically make things work in different locations anymore than ROOT will. Adding paths to *PATH environment variables will be required and that's a manual task that you'll need to do. In short - this seems like an awful lot of hassle for absolutely no gain. Most of us consider the current directory structure to be quite clear.

To create a very clear directory structure for a small binary Linux distribution I am planning to build using Gentoo and Portage. This doesn't make sense to me. ROOT is the option to specify another ROOT directory. The layout below that ROOT might be configurable for some applications, some other are expecting their files in certain paths. You can override the configure settings, but this won't win you much since some programs don't use autoconf (and there's good reason not to use this can of worms!). Also, the applications' behaviour is absolutely untested (e.g. some apps simply rely on finding their initial data below /usr/share, being able to write to /var/run and so on). This is why we have good package managers on Linux. They deal with the logical structure (i.e. packaging) of the files. BTW, ROOT will win you nothing here since you want to create binary-packages, not install them. Maybe you can try and mangle the archives, so that they resemble the directory structure you want. But I still can't see how that could overcome applications' built-in assumptions, except you are thinking of tricks like unionfs or (hard/soft-)linking into a LFS-oriented structure after installing the packages. -hwh -- [EMAIL PROTECTED] mailing list

-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Hi, thank you all for your very clear and thus helpful statements. I am going to reconsider my plans. Maybe there are better structures. Or maybe I'll simply keep the gentoo-style structures and place some folders with symlinks under root. Anyways - thanks It's always a pleasure to post here (at least as long as people are not flaming on some semi-interesting subject. :) ) Many Greetings Paul -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGOJCSaHrXRd80sY8RCpkbAJ97hnxcXTVk6s1BdJWBBxa4YNO5dgCgzrm1 NMEiU+yOLwzYkv6zhNqJ02A= =/cxF -END PGP SIGNATURE- -- [EMAIL PROTECTED] mailing list

Re: [gentoo-user] Setting installation directories globally
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 I thought about that too, but wouldn't that more or less create a new system. For instance if I emerged a library (say libpcap) with ROOT=/libs and then tried to emerge wireshark (which depends on libpcap) with ROOT=/analysis I think that wireshark would fail to start due to missing libraries. (Or it would pull in libpcap once more and merge it into /analysis thus resulting in several installed copies at once). Please correct me if I should be mistaken.

As far as I know there is no way to change the prefix via portage, since its
all hardcoded (kinda makes me wonder why this was never added as a feature
tho). My best guess is that you're going to have to setup an overlay. This is
what I would do (untested tho):
copy any ebuilds to /usr/local/portage/{category}/{app}/whatever.ebuild
rename that ebuild so its version number is really high (like 9) so portage
will default to it instead.
change the prefix in the ebuild
Install via emerge. I don't think I've ever seen anything in stable with a
version number that high, so as long as you make sure that the ebuild is in the
stable tree and you're not using unstable packages it *shouldn't* ever emerge
over it. Down side is you will have to do this everytime you want to update
the package.
Kinda a halfass way to do it, but I think it would work.

Makes me wonder, too. I'm starting to think about writing a patch. It should be somehow possible to let portage override the settings within the ebuild. However I have never hacked up emerge before. Any suggestions by the pros out there? My best guess is that you're going to have to setup an overlay. This is what I would do (untested tho): Yeah, I thought about that too, but it pretty much eliminates the point of using Portage in the first place.
