: This means I'm going to disconnect these drivers on Sunday. I posted a

: - It seems I forgot to mention ucycom(4) and ufoma(4). These have not
: been ported to the new TTY layer.
:
: This means the complete list of drivers is:
:
: | USB: ubser(4), ucycom(4), ufoma(4)
: | ISA/PCI: cx(4), cy(4), digi(4), rc(4), rp(4), si(4), sio(4)
: | Line disciplines: ng_h4(4), ng_tty(4), ppp(4), sl(4), snp(4)
This is a lot of functionality to remove on such short notice.
: There are a couple of important things to mention here:
:
: - Some line disciplines (ng_h4(4), ng_tty(4) and snp(4)) will be
: restored in the future. After the new TTY code has been imported, a
: hooks interface shall be developed, which will allow these drivers to
: work once again.
Can't you push off the import until these things are done. There have
been too many empty promises in the past to accept this at face value.
: - PC98 still uses the sio(4) driver. I've decided not to touch PC98 at
: this moment. I'll contact the PC98 folks one of these days, to see if
: we can already perform a partial migration to uart(4).
:
: Wrapping up, I'd like to say I really hope we can one day see these
: drivers reappear in FreeBSD. Fortunately we've still got a long time
: before 8.0-RELEASE.
You are moving too fast on this. Please slow down. You promised
documentation and such, but that hasn't happened, so a slowdown in
your timeline is justified.
thank you for your consideration.
