ash incompatibility

[Sergey Naumov]

Hello.

I have tried to execute following command on busybox's ash:
# ps | grep `fuser /dev/ttyS0`

On host's (Debian 5.0.0) ash it results in normal output:
# ash -c "ps | grep `fuser /dev/console`"
2002 root /usr/sbin/ledstats

but on embedded system it prints
# fuser /dev/ttyS0
902
# ps -o pid,comm | grep 902
902 sh
# ps | grep `fuser /dev/ttyS0`
grep: 3809: No such file or directory

Busybox config is attached. Bash compatibility is enabled.

Sergey Naumov.
