su, scripts and distributed-net

[Joe Drew <hoserhead@woot.net>]

I've been working on updating distributed-net to the new versions of
the clients, and have run into a snag:
When the distributed-net-config script is run, distributed-net (or
dnetc as it calls itself in the ps listing) locks up hard. An strace
of the process from the su comes up with this:

ioctl(0, SNDCTL_TMR_START, {B38400 opost isig -icanon -echo ...}) = ? ERESTARTSYS (To be restarted)
--- SIGTTOU (Stopped (tty output)) ---
--- SIGTTOU (Stopped (tty output)) ---

repeated over and over.

An strace attached to the process itself comes up with this:

gettimeofday({946949783, 688322}, NULL) = 0
ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0
ioctl(0, SNDCTL_TMR_START, {B38400 opost isig -icanon -echo ...}) = -1 EIO (Input/output error)
read(0, 0x40015000, 1024)               = -1 EIO (Input/output error)
ioctl(0, SNDCTL_TMR_CONTINUE, {B38400 opost isig icanon echo ...}) = -1 EIO (Input/output error)
nanosleep({0, 50000000}, NULL)          = 0

again, repeated over and over.
The exact su command, on the command-line, works perfectly. 

If anyone can help, the .deb, .diff and .orig.tar.gz are available at
