I'm not seeing anything new printed in dmesg after the original pty gets
closed. I do see the first "Virtual console 0 assigned device '/dev/pts/5'"
printed during boot, but nothing after closing the pts device. Do I have to
enable something somewhere to get uml to reopen after close?
This is 2.4.22-5um, 2.4.20+skas3 on the host...

host% uml_mconsole uml config con0

I don't know if it is relevant, but the uml's dmesg contains the lines:
Checking that host ptys support output SIGIO...Yes
Checking that host ptys support SIGIO on close...No, enabling workaround
Thanks
