From 23 Feb 2012 newspage http://www.slitaz.org/en/#news
The SliTaz contributor team is pleased to announce the immediate availability of the first release candidate for SliTaz 4.0. SliTaz can boot in 10-12 seconds on fairly new hardware and with the new 4in1 ISO you can install a full SliTaz desktop with only 48MB of RAM. The 4in1 ISO is able to auto detect the memory and can boot SliTaz in text mode, a minimal X environment or a full graphical desktop.
Still unclear where to find clearest up-to-date Hard Drive installation docs for 4.0-RC1
Also, still bit of confusion on minimum system HW reqs for full graphical desktop installation.
