While it is nice to have /home on a separate filesystem, and it's generally how I do things on a desktop, moving it is a lot of work just to reinstall. -- Neil Bothwick New Intel opcode #007 PUKE: Put unmeaningful keywords everywhere pgpGBpTRs72fB.pgp Description: OpenPGP digital signature

Are you logging in as root?! THAT'S DANGEROUS! Probably not, you are probably misunderstanding me. I've just checked, on my system, root's home is /root, which is as it should be. Is your home /home/username, or is it /username?

"home" data would not be touched by upgrade. > > Ahh ... you didn't say that! That changes everything! Okay. I would look to free about 380GB (just enough) at the end of the disk to create sda5 which will be (at least temporarily) your new /home. LOGGED IN AS ROOT just mount that on /mnt, and copy the contents of /home into it. Now using your gentoo install disk delete sda4 and split it into two - your new sda4 for your new gentoo, and a new sda5 (AT LEAST as big as one you created in the last step), which will shunt the partition you just created into sda6. Install your new gentoo. Now you've got sda4 (/), sda5 (which will be /home), and sda6 (where you've just copied your old /home). Mount sda6 on /mnt again, and copy it to /home (sda5). Finally, delete sda6, extend sda5 to use the space you've just freed, and expand the filesystem on /home to use the full size of the extended partition. That'll probably leave you with a 150GB /root, but that'll be plenty I expect (and a 760GB /home). Cheers, Wol

Don't forget to edit > /etc/passwd if you have to move it. Can you elaborate pls.? My current "home" is in "/"; so why move it there, it is already there. I don't have extra disk around, but I could copy /home over network to another PC. I was planning to move "home" to another partition as I plan to wipe old installation (it is impossible for me to upgrade); it will be easier to reinstall. My old installation is: Portage 2.3.24 (python 3.5.4-final-0, default/linux/amd64/17.0/desktop, gcc-6.4.0, glibc-2.25-r10, 4.9.72-gentoo x86_64) Since, old installation has home or "/" (root) partition, if I wipe the root, home will be gone as well. So I was planning on moving "home" to another partition, this way all data will be there. So, after moving "home" to another partition "sda5" I can wipe the "sda4" and re-install gentoo. "home" data would not be touched by upgrade.

Couple of things. Firstly, why use a gentoo live disk? Just log in as root. Secondly, why rename home? Just mount sda5 on /mnt to do the move, then add it to fstab to mount on /home. And a little bit you might have missed - DON'T put root's home on a mounted disk - if it's currently in /home, move it to /. Don't forget to edit /etc/passwd if you have to move it. If everything works, remove /home.org Stage-2: With Gparted resize both root and home portion, giving root about 200GB and rest to /home (dev/sda5) The other way to do it is if you've got a spare hard drive lying around. Just copy /home onto it (bearing in mind my comment about root's home), and then copy it back. But what do you mean by "save drive"? Just splitting the drive into 2 partitions won't do anything, will it? If you want to "save the drive" I think you need to move /home to spinning rust :-) Unless you're physically updating the hardware, I wouldn't bother. Cheers, Wol
