From: Ignoramus17356 on 6 Apr 2010 11:41 I have decided that I need to take back a statement that I made. I said that having encrypted partitions is a must. I no longer believe that I can run several distros on encrypted partitions. Something has to give, and I think that it is more important to try several distros, than to have an encrypted partition. Once I settle on something, I will reinstall and get encrypted partitions. I have these reinstalls down to the science now and it is very easy to reinstall stuff and restore my settings. i

I have no experience with LUKS yet, but all I know about it leads me to expect that you can do it. - anton -- M.

Redhat distributes and those that started life as derivatives, like Mandriva, assign USER IDs starting at 500. Ubuntu starts from 1000, I assume that Debian probably does the same thing but I don't know. If you want to share the home directories you will have to edit the /etc/passwd and /etc/group and /etc/group- files to make them consistent. What you need to do after you've done an install is to first log in as root and fix the files. Ubuntu doesn't enable a root user so you'll have to do it a little differently there. The procedure for Ubuntu is to set up the partition table during installation so that there is no /home partition, name it something else like /user. Ubuntu will then creates / home as part of the root partition and gives you a fresh home directory. When you log in the first time you'll have to edit an additional file, /etc/fstab. Do an umount of /user or whatever you've called it, change the mount point in /etc/fstab from /user to /home, do the /etc/passwd and /etc/group edits to make the user name consistent with the other distros and then mount /home and log out and in again, or do a reboot. You can also do this with webmin if you aren't comfortable with editing /etc files (although you'll see that the formats for these files is simple and obvious). If you install Webmin you will be able to change user and group numbers using Webmin's System/User and Groups module. You can also change mount points with System/Disk and Network Filesystems. |
