Not so big problem for me, so I used mount --bind for dirs I want to share (ie /usr/portage as I'm using gentoo) and it took only about 100MB.. so not a big deal > >> 2) More administrative to keep chroot system updated > >> 3) harder to check, that autotools won't pick something from buildhost > >> in normal environment before pushing new version/recipe (ie I won't > >> have SDL libs installed in chroot, but everybody else will and maybe > >> build will fail for them after I push some recipe. > > > > I see this as a good thing :) The last point? Well it's good for me (less issues) but if I push some recipe failing for 99% other builders just because they have pretty standard libs on their systems, then I should be blamed for pushing crappy recipe :). > Seems a good plan to me, please keep us posted. > (actually I've been considering building in a minimalistic VM) Well VM would be much slower.. If someone is interested in that chroot I can push tar.bz2 somewhere.. but I guess that it's not needed (as it's only slightly stripped stage3 gentoo tarball). Additional apps built (qemu-kvm just because I have ASSUME_PROVIDED for that as there is mmap issue fixed in that newer version) qemu-kvm diffstat texi2html cvs screen subversion git bitbake /etc/make.conf and chrootOE.sh I'm using in attachement Regards, -- uin:136542059 jid:[email protected] Jansa Martin sip:[email protected] JaMa
