As for the "embedded" Tynux: That's a different one :). There's also a Linux based IP-Phone, called TyNuX and a Linux-on-a-floppy ditribution with a similar name. Our tynux is none of that, it's basically a distribution which slaps a kernel, a shell (ash) and some tools on your harddisk, waiting for you to compile a full glibc, etc.
Initially we all thought this would be fun to do. With a preliminary 0.8 release the problems started. Self- proclaimed Linux Experts started sending flames regarding the lack of editors (we DID include ed), Perl or Python (download and compile) or their inability to do a fdisk, mkreiserfs and lilo on their own (the installer drops you into a shell when these things are required).
