Hi Lauri,

 you are right the environment is different, so different binaries are
called.
 Yes, the problem is related to mount exit status which is wrong.

root at box:~# which mount
/bin/mount
root at box:~# ls -la /bin/mount
lrwxrwxrwx    1 root     root            12 Aug  9 17:52 /bin/mount ->
busybox.suid
root at box:~# mount -o remount,rw /mnt/sr0; echo $?
0

 Thank you,
