Re: Include DaynaPort by default in GENERIC?

HI Jason,

some parts here are a bit nostalgic, but compelled me to comment.

Some slimming down might be specific to SPARC, but also for other 
kernels used on older or small system, like most 32bit systems nowadays.

Never touched these, but perhaps there is software relying on them? 
Curiosity.

I too wondered if that works at all anymore... and how, would you need 
some kind of userland?
I guess it is really niche use, if at all.

Maybe access to large hard disks nowadays or SCSI to other format 
converters?

I use NFS daily as client and server... but indeed more and more "other 
way" around, that is sparc32s are clients to more systems with servers 
and large disks.
But most probably a module would be best.

No, I suppose not... except a note below for PPPoE which is/was used for 
several DSL services, like those modems which are not routers but attach 
through the ethernet port. I do not use them since several years now, 
but wonder if someone still has them in other places of the world or 
with other providers.

"real" PPP is probably long dead with internet providers, except if 
somebody is doing some point-to-point connection on their own?

scanners I presume not... chnager devices as in CD changers=
Maybe somebody though has nice serial attaced disk arrays :)

I don't.... but maybe omeone has nice SunServers or such!

I suppose SLIP is no longer used since the '90ies when I connected with 
14k4 modems, or?

hmm long time ago when I could get a pack of hard disks and build small 
NAS... but one could argue that it is niche enough that somebody can 
build it.
Could that be a module too?
