Maybe I missed something in the doc, but after the creation of /etc/fstab I have seen nothing that insists on manually mounting partitions that may be of use for the rest of the installation process : I stumbled in that step when, having defined /opt, /var, /home and /usr to be set each on its own partition, I forgot to mount them explicitly after having defined my fstab. Therefore all files which were to be in these paths got installed under / and, after rebooting, the system was unable to find anything under those paths, since fstab settings had eclipsed the directories under /. I ended up with a somewhat incomplete system with /opt, /var, /home and /usr being empty. I corrected that by mounting these partitions elsewhere, thus making their counterparts under / visible, and copying everything to these new mount points. At reboot everything went fine. I think a simple sentence in http://www.gentoo.org/doc/en/handbook/handbook.xml?part=1&chap=8#doc_chap1 would do the trick. Thanks for your great job ! Reproducible: Always Steps to Reproduce: 1.make your fstab with for example /usr being on another partition 2.do not mount it manually 3.go on with the installation process
The mounting of partitions is done right after creating them (http://www.gentoo.org/doc/en/handbook/handbook.xml?part=1&chap=4#doc_chap10) It doesn't explicitly mention that, if you have defined other partitions, you should create the appropriate mount points and mount those too, I'll add that in a minute.
The handbook has been updated.
