In short: yes, I think so. It Looks to me like a new profile that uses proper multilib (something that some Gentoo devs have been working on for several years now, in fact) instead of the pre-compiled 32 bit packages (app-emulation/emul-linux-*), so that now, finally, (some) packages can be compiled for both 32 and 64 bits. Specifically, I think it is explicitly for wine users. Actually, I'm mildly excited that proper multilib (at least for amd64) appears to be nearing completion, or at least a usable state. > If so, I have a few more questions: > > Is it stable? > > Is it worth to choose it while installing a new Gentoo system? No clue about these two, since I haven't tried it, but I've never heard of "experimental" profiles, so I don't expect it to be broken (but see below). Anyway, I just switched to default/linux/amd64/13.0/no-emul-linux-x86/desktop as an experiment and am waiting for emerge @world to finish :) . So the no-emul-linux-x86 profiles are fairly simple: they unmask the abi_x86_32 USE flag (at least for enough packages to satisfy wine's dependency tree), mask the emul-linux-* packages, and mask some older versions of packages that don't have the necessary multilib support. I needed to upgrade 5 packages, of which four (gnutls, texinfo, nettle, and libSM) have open stabilisation bugs. The one without was wine, but I don't mind in its case. After that and adding lots of abi_x86_32 USE flags, portage was able to sort out all blockers by itself and emerge @world started running successfully. There is also a corresponding abi_x86_64 USE flag that remains masked, so you don't get the full granularity yet, but it will get there eventually :) . > Can I expect that in this case I will be able to install > and run such applications as, say, wine? I would expect so. The wine ebuilds (at least for version 1.7.x) have supported multilib for a while now (just check the changelog), as an alternative to the emul-linux-* packages. > Thank you.
