Hi Sergio,
Just curious - what does SMB have to do with being a portable system?
Because some people use it and some don't.
SMB is used to share files to/from Windows systems (primarily). I
literally couldn't do my job if I couldn't hit windows shares - it's a
huge deal for me (and my co-worker who is thinking of switching to
Fedora).
Sure the package could be installed, but he was ready to give up on
Fedora because he couldn't hit shares, nor could he figure out what
package should be installed.
That's why Fedora isn't for first-time users. If he had a minimal
experience he would search for samba and could install and run even from
the live-CD.
Now, that's not saying it shouldn't be shipped in the spin. I don't use
it but if people think it should be shipped, like because it's small and
useful, then fine for me.
