SYSADMIN’S DELIGHT
MIN SPECS: N/A
Finnix is a small distro with a big history. It was discontinued in 2000, resumed in 2005 and was one of the first live distros especially geared for system administrators. There was no live booting to a GUI at the turn of the millennium, and neither is there in today’s Finnix. That’s why the ISO is a positively petite 412MB. Sysadmins don’t need GUIs anyway. No, they need SSH configuration from the kernel command line, on-hand access to all the filesystem tools, and logging in to a root account by default. Oh, and Midnight Commander installed out of the box.
