Hello, I am planning to use SuSe Linux 10 Live-DVD for practicing Linux. Although, I can install any version on my laptop and work, but I dont want to disturb/touch my 'Windows' laptop just for practicing Linux, then I heard of run-from-DVD Linux, and I want to try it. My question is: With Live-DVD can I do things like make/remove files/directories, change config of apps and OS, ifconfig, du, dk, vi, awk, perl... etc. Also, would I be able to install/remove packages and patches? (or simulate atleast) Please help me with your advice.

The easisest asnwer is to think of the DVD for what it is. A nonewritable disk. What you get is a full operating system plus applications all running from a DVD. If you burned to a re-writable disk then you may be able to tinker but that is not the way it is meant to be used. It is meant to popped in and run as it is. You could certainly save to any hard drive that was installed on the PC. -- ============================================== I am only human, please forgive me if I make a mistake it is not deliberate. ============================================== Take care this Xmas.

Please do not use html email on this list. Since the "live DVD" runs in memory you cannot save data to it and cannot install any software, sorry. It would be nice to do so for people that want to "practice" running SUSE linux. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998

One limitation I've encountered, is that you can not use the DVD-image on a net-booted environment, like the "live-asterisk" image... The point where the initial scripts mounts the dvd-rom (and I want to replace it with a NFS-mount) is binary, instead of a shell-script.

Ken, The liveDVD is not as read-only as you imply. It is my understanding that portions of the SUSE live distros use some kind of specialized RAM/DVD based filesystem when they run from the liveDVD. If a disk block has not been written to, then a read goes to the DVD. If a write occurs to this specialized filesystem, then the updated data is maintained in RAM. Of course that data is lost on reboot, but for training/learning that is not necessarily bad. I did some testing with the 9.2 liveCD a while ago and found: After login "mount" shows / as (rw) read/write. I could create files and folders in /root, /etc, /var, and /tmp. I modified /etc/motd. I then logged in on a different virtual terminal, the new motd was displayed. Thus parts of the 9.2 liveCD setup are definately read/write.. I tried to create files and folders in /usr, but that failed so it is readonly. Default rpm installs fail because of the above. I did not do any real work to figure out how to install rpms in an alternate way, nor to promote /usr to r/w. Hope that's informative at least. And maybe someone else can explain how to do software installs. Greg -- Greg Freemyer The Norcross Group Forensics for the 21st Century

Yes you can save -small- amounts of data to the virtual drive but as you say it will not be saved. Since the filesystems that save data from a software install are read-only you cannot install even small software packages. As stated by another poster you can save files to a flash-drive or usb mounted harddrive but saving any where else is fruitless. Better to tell new people they cannot save data then have them wondering where the saved data went to on a reboot. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998
