I have worked on Slackel 6.0.4 a new release. The main target was the testing of installing on efi gpt partitons with grub. This is done by grubconfig which is part of grub package. Slackel 6.0.4 openbox 32 bit image includes both PAE and non-PAE kernel with older hardware support.
The source code of iso-creation scripts from gapan, which has been changed a bit since Slackel has root user also, used to make the iso can been found on github
The source code for grub package is here where can find the SLKBUILD and grubconfig for salix also.
grubconfig script has been further developed and installation has been tested on efi gpt as well on bios pc's.
updated grub package will uploaded to package submissions.
Also installation using (e)Lilo also has been tested.
A video for installing slackel 6.0.4 64bit on efi has been produced to help users.
This is good also for the future releases of Salix.
