You don't need pm to do backups. You _might_ need it to resize your partition, but as far as possible use Linux tools. I resized a Windows 98 partition using FIPS which came with Red Hat Linux. I backed uo the whole drive first, using dd to copy it to a file across the LAN, gzip to compress the file and cdrecord (maybe mkiosfs too) to create a CD. All standard Linux tools. > > 2.

May not need it now or for a few years, but when that time In a few years the picture will be very different: different supplirs, possibly some of the current ones gone, maybe some new ones. Turbolinux was one of the first on S/390, but it hasn't had much mention here for ages now. > comes, it is easier than converting to a different distribution to get > it.)

And also any application venders, PeopleSoft etc. There too the picture's changing rapidly. According to articles on The Register in the ast 24 hours, Oracle "just loves linux," PeopleSoft & J D Edwards are converting their apps to zLinux as fast as they can. > > You may find you don't really have any options. > > Perhaps do the first one, and trash it when the study on the second > option is completed.

I imagine that term refers to SuSE Linux - there's no release 8.1 from Red Hat, and Debian's at 3.0. > If you are a REXX type, install Regina (the Rexx for non-IBM > platforms).

I guess if you're using it on everything else, then using it on Linux is sensible. Otherwise, I prefer to use tools you can expect to find wherever you go on Linux, and that means bash (shell), perl and maybe python. Ruby seems to be becoming popular, and there's also TCL (with TK). > FWIW, I did the same thing. I picked Suse (with option 1), and as it > turned out, worked with the Option 2 concerns.

Maybe, a document to produce. btw There's an open source program called User Mode Linux, hosted at sf.net. Like VM it lets you run several Linux instances simultaneously on one box. AFAIK it's only available for IA32, though someone was porting it to PPC. I used it to run Red Hat Linux 7.0 on Red Hat Linux 6.x. -- Cheers John.
