I checked the savetextmode on my debian 2.0 system (svgalib 1.2.13): [root@goodguy(11:10am)-~]%cat /usr/bin/savetextmode #!/bin/sh set -o noclobber restoretextmode -w /dev/stdout > /tmp/textregs restorefont -w /dev/stdout > /tmp/fontdata The noclobber keeps it from overwriting any files. However, from the origianl svgalib source the script looks like this: [root@goodguy(11:13am)-~/svgalib-1.3.0/utils]%cat savetextmode #!/bin/sh restoretextmode -w /tmp/textregs restorefont -w /tmp/fontdata This WILL overwrite any files. So if you use the base svgalib, then you have a problem. NOTE: The Debian package for svgalib 1.3 directs the output to /etc/vga, so it is safe. I'm not sure if redhat has this changed or not.
