hi, i'm getting ready to install Gentoo on my box. i already have mdk 9.2 and slackware 9.1. I think it would be waste of space if i setup some new paritions again.

on top of it, i'm just trying to get a feel of the diff distro, in fact...mdk is still my main OS in my box (probably because i'm too lazy to mess with slack :P )

so here's what i'm thinking:
can i do something like --- 3 /, 1 for mdk, 1 for slack, 1 for gentoo
then they all share /home , /opt, /swap, etc

that way, its not only save spaces, i can also access to the same application/file/programs regardness which distro i'm in.

can that be done? if so what else i need to watch out for?
if not, got other suggestions to offer???

thanks

They can definitely share the swap and /home partitions. I have it set up with swap, /home, root for gentoo and root for slack. I can mount one root partition from the other. I've run my gentoo grub from slack before, so I would think you can run apps regardless of which system you're in, but don't take my word for it.

You can share swap. Home is ok but you will have different uids for your same user. MDK might have your userid at 500 for one distro but another will start at 1001 so you will want that fixxed. Also a lot of hidden files are in your home dir. I would consider a seperate home dir for your stuff and have a diff user name for each distro. Or change all userids to the same number. Beware of verrsion differences also. /opt holds KDE. I hope all of the distros use the exact same ver. All of the above are imperfict answers YMMV. To be safe share your swap and use the same userids in all of your distros.
