hi!

i start my UML (2.6.17.3, host 2.6.16.9) with:

start-stop-daemon --start -r /home/uml/chroot -v -c uml -x linux
mem=128M ubda=root_fs ubdb=swap_fs con0=fd:0,fd:1 con=null eth0=tuntap,tap0

which works fine. (tap0 has been configured on the host with tunctl -u
uml before.)

my problem is that backgrounding does not work. :-(

when i run the above command with the -b option set, the uml stops
running after a while - or is at least not reachable through the
network. ps aux shows:

uml       3040 28.2  2.9 131432 15012 ?        Ss   22:02   0:10 linux
mem=128M...
uml       3046 12.0  0.1    660   604 ?        T    22:02   0:04 [linux]
uml       3050  0.0  2.9 131432 15012 ?        S    22:02   0:00 linux
mem=128M...
uml       3051  0.3  2.9 131432 15012 ?        S    22:02   0:00 linux
mem=128M...


when i try to run uml as root without chrooting and background it (& at
end of command line) i get:

[1]+  Stopped                 ./linux mem=128M...


ps aux then shows:

root      3012  1.9  0.7 131172  4060 pts/1    T    21:58   0:00 ./linux
mem=128M ...
root      3018  0.0  0.7 131172  4060 pts/1    T    21:58   0:00 ./linux
mem=128M ...
root      3022  0.0  0.7 131172  4060 pts/1    T    21:58   0:00 ./linux
mem=128M ...
root      3023  0.0  0.7 131172  4060 pts/1    T    21:58   0:00 ./linux
mem=128M ...

i can reactivate uml with "fg" though.


any idea what is wrong? it's pretty irritating, as i want to start the
uml on system boot, which can't be done without backgrounding the process.
