If you set "GRUB_DISABLE_RECOVERY=false" in "/etc/default/grub", the
boot submenu will have single-user entry for every kernel.

If you set "GRUB_DISABLE_RECOVERY=false" and "GRUB_DISABLE_SUBMENU=y"
in "/etc/default/grub", the enu will have single-user entry for every
kernel.

I used LaTeX and Inkscape for most of my drawings in my doctorate
dissertation. Though I did not use much of the built-in LaTeX
integration within Inkscape itself, for my documents I exported
drawings as .png or .pdf for better quality and used them as figure
environments. Inkscape is a good portable tool for such things. I used
a Makefile for automation and building of my thesis instead of bash
scripts to assemble the PDF.

Book/Paper technical illustrations - inkscape?

2017-04-05 Thread Keith Lofstrom 
I am considering Inkscape as a technical illustration
tool for latex documents (papers and book chapters). 
Suggestions for better tools? 

I usually set up bash scripts (with lots of comments)
to automate the assembly of my documents, rather than
use graphic environments like openoffice. I am NOT
looking for a complete document design tool.

I have Inkscape running now in SL7.3, though it has
a strange rendering problem (overlaid windows leave
translucent ghosts) that I'll need to fix if I want
to use it for production.

P.S. I've used a hodgepodge of drawing tools over the
years for patents and papers and presentations and CAD.
Most are old and unsupported now, or worse, the tools
change interfaces to adopt the latest fashion.  I want
to think about my content, not admire the cleverness
of the toolmakers.  The best tools are like wallpaper,
and fade into the background.

If you want KDE 3 on SL6 or SL7, use the Trinity Desktop (

Just to be clear, when I say "ZFS is native in Linux" - I do mean
included and available as a build option in the upstream Linux kernel.
In my opinion, the OpenZFS [1] effort is not "native" in this regard.
