Hi all,

I used Gentoo back in the day, say early 2000s. After that, I transitioned to Linux From Scratch, then to Debian, and finally Ubuntu. I was at my box the other night and I was bored. I mean, Ubuntu is easy, but it just doesn't have that old feel that I could always tweak something here or there and get something better.

Anyway, I re-partitioned my laptop this morning. I have a swap, a / for Mint, a / for Gentoo, and /home. My major question is will sharing /home between two distros cause any problems?

Mint will be running Cinnamon. I'll probably run XFCE or KDE under Gentoo. I hope they will share the /home/user/.mozilla and other things without screwing each other up.


Also, since I have a working Mint install, where should I start with the Gentoo install? No real need to boot from the install disc, right? Is there a short how-to somewhere for installing from a running linux image without borking the original install? I guess I'll update the boot manager from the Mint side. Although, I really don't know how much that matters. I just don't want to get stuck with a broken bootloader if I bork the Gentoo side.


If anyone has any tips for dual-booting Gentoo and another distro, please let me know.


Thanks all...

There is no definite answer.
The better those installs are in sync (running the same version) the less trouble I expect. While forwards conversion is usually no problem, reverting to an old version (of the config files) can be impossible.

OTOH, having some toolkits/themes installed (and in use) on one system, while not having on the other might have some effect on the appearance.

The only difference is, that you already have a installed (and therefore fast) system. apart from that (and that you do not want to screw up your existing install) the procedure remains the same.

Chose one bootloader (and distro) to boot from, and perform any changes there.

To share /home, you need to ensure that the UID and GID for your user are the same on both systems. Also it can cause problems if you run different versions of Firefox/LibreOffice on the two installs.

/boot can usually be shared without issues. swap too, if you don't use suspend-to-disk.
