Slax 6 is small All Slax modules are much smaller then any other compressed packages available nowadays for all other Linux distributions, while the speed of decompression remains usually faster then reading the full data from disk.
Slax 6 is portable Thanks to the AUFS filesystem, the read-only part of Slax (system data and modules) is overlayed by a writable filesystem. You can modify all areas of the filesystem in Slax without any restrictions. In Slax, you are not limited to just a persistent home directory - the whole root filesystem is fully writable, so we talk about 'persistent changes' (rather then about 'persistent home', known from other live distributions). You can modify /bin/bash the same way like ~/kderc.
Slax 6 is feature rich XWindow system, KDE desktop with K-Office, Internet browsing, e-Mail, Instant messaging, CD/DVD burning and ripping, Audio and Video encoding, Multimedia players, all and even more is included in just 190MB of Slax OS.
