That's what pissed me off so badly about Ubuntu. I carefully partitioned the disc on cylinder boundaries, and told the installer to use the existing partitions. Then it went away and did its own thing, all to save a quarter or half of a cylinder. It did the same thing on the text-mode install procedure.

But that won't preserve an existing installation.

I think it's significantly better than apt-get. You can do "sudo yum upgrade", which does the same thing as your sequence. The thing I really like about yum is "whatprovides", i.e. "go look through the entire package database and find which one provides the obscure library that my poorly-packaged program needs." That's saved me a lot of time over the years.

But that won't preserve an existing installation.VMware Converter creates VM images from existing installations. Note that I have only used it on Windows and have *not* tried it on a Linux box, but I have been told it is pretty straightforward with most systems. Whether it is worthwhile depends on the devices involved. Obviously there is no point if you depend on some bus card device that can't be transported to a newer host. But VMware has no problem with USB, serial, parallel and most SCSI devices - it even handles many of the partial SCSI implementations typical of printers and scanners. George

You and I seem to be having an interated failure to communicate on some of the other issues, though. It's hard enough future-proofing one's computing installations without having the tools decide that they won't cooperate.

We use a number of Freescale Kinetis devices, butI forgot to mention the Infineon XMC4000, no "recommendation" since I don't use/know it, but as far as I see, it has a serial bootloader in ROM.

Linux has always been, at least for me, 'if it does not exist write it'. or sometimes 'I cannot be bothered to learn this ..i*t' so I will write my own app. Old Dutch saying (and I am sure it is universal): One should not look a given horse in the mouth. And 'I want Linux to be compatible with Microsoft <whatever>' is NOT on MY list of priorities. As to 'future proof', not one new kernel I tried had the same bugs as the previous ones. And the driver API changes, video4linux, the DVB driver, OSS , Alsa, etc etc, changes every year or moon phase or sunspot, have not figured out when exactly .. Meaning you have to rewrite your apps every time in many cases, including all scripts (command line flags change...). Now YOU did chose Linux, so get used to it. All that, mind you, I ONLY run Linux, except for an old win98 but that seems to not understand the new graphics card, so its screen is now so messed up... should delete it.. but has my scanner driver.... Not that I use the scanner, I use the camera... Anyways future proof what year did you have in mind? In the computer world 6 month is already an unknown, 6 years ? 60? Maybe we all have a chip implant by then, and only need to _think_ to partition our brains.

And here I thought that the >communication failure was accidental.The communication failure was possibly the channel that told you Linux does everything, and you believed it. BTW if you dont want some scripts to call some routine (program) (say fdisk), rename the orignal mv fdisk not_today_fdisk , make a small script called fdisk that returns OK (exit 0), and see what happens (if anything). I do things like that sometimes to 'stay in control', you can make it log to with 'echo'. Sometimes it helps, and sometimes it does not, modifying the source a bit does the same. Yes it is hard work, I spend a full day programming asm, it is hard work too, especially if you want zero errors. Maybe it will erase all your disks, YMMV ;-)

(Crunchbang Linux is also in the run.)I have used openSuse for quite a while. If you want better EDA tools fedora may be best. *buntu make me uncomfortable about security. Maybe it is time to try Debian or a derivative again. I prefer package (dependency) manager style Linuxes currently, though i can and will at need install from source. ?-)

Roberto Waltman <usenet@rwaltman.com> writes:> Cross posting to sci.electronics.design > > What linux distros do techies like?I have Debian in my home desktop and NAS, Sabayon in my personal laptop. I picked Sabayon for the laptop to get new stuff quickly since it's a rolling distribution. So small weekly updates instead of a huge one twice a year like Fedora or never like Mint... For chip design work (at work) I've usually used RHEL or CentOS since that's what the tools officially support.
