Linux-Live-system inc. Ruby 1.9 on USB-Stick with r/w-Partition

well guess that many of you have great expertise on Linux. I currently have some issues with creating a linux-live-medium.

i have a box with OpenSuse-Linux Version 11.3 with all nice things. Several languages run very well: Perl, Python, PHP! All is very well! BTW - i am very glad that Perl runs very nice.

But I am not able to install Ruby 1.9. Everytime i want to do that i end up with Ruby 1.8.7. I want to testrun some ruby-code. Therefore i need Ruby with the following gems

mechanize nokogiri utf8_utils

I heard of a Linux-Live-medium that is able to run with all the wanted things including Ruby 1.9. Therefore the Live-medium is installed on a USB-Stick with R/W partitions. Is this possible.

I am not a linux-expert - but with all the expertise here i think it is possibl开发者_如何学Ce to create such a USB-Stick. (...with Ruby 1.9 and all with all that extensions) I love to hear from you!

best regards zero

Debian/Ubuntu includes both Ruby 1.8.x and 1.9.x - and essentially duplicates most packages in 2 flavors: for 1.8 and 1.9. That might be enough for your purposes - although YMMV, of course.

Yet another solution is RVM that karudzo already mentioned.

Yet another solution is virtualization: simplest form of it would be just chrooting. Most modern Linux systems have an ability to install itself based from some root directory (SuSE has install into given directory functionality, Debian/Ubuntu have debootstrap - and then just running chroot /path/to/that/directory - you'd end up in essentially another system installed cleanly in separate directory.

This will actually be a better solution for you- use RVM:

Then you can easily switch back and forth from 1.8 to 1.9 as desired and make 1.9.2 your default. Just read their docs carefully, it really makes gem management a lot easier.
