MilaX 0.4 is released. MilaX is a Solaris based Operating System & is a small size Live CD distribution which runs completely off a CD or a USB pendrive.
What originally started as an experiment to see how much Solaris software could fit in miniCD eventually became a full-fledged OpenSolaris distribution. It is also possible to use MilaX as a Rescue-CD.
It was designed to run graphical applications on older PC hardware & can be installed on storage media with small capacities, like bootable business cards, USB flash drives, various memory cards & Zip drives. Available for both x86 & SPARC platforms. MilaX is free to use, modify & distribute.
MilaX requires at least 256MB RAM & a Pentium or Celeron to boot into a X desktop. 128MB RAM is sufficient for booting into Command-Line mode. MilaX is a fast distro (~20secs from GRUB to fully functional desktop after ZFS installation).
