1.3.10: cygrunsrv dumps core when passwd not present (.NET Server)

- Subject: 1.3.10: cygrunsrv dumps core when passwd not present (.NET Server)
I attempt to install sshd through cygrunsrv from a batch script during Windows
install time with
cygrunsrv -I sshd -p /usr/sbin/sshd.exe -a -D
This is executed *before* /etc/{passwd,group} are created, and as the SYSTEM
user.
It comes back with the error:
cygrunsrv: Given path doesn't point to a valid executable
The file is there, and perfectly valid. A trace shows that cygrunsrv is dying
due to a STATUS_ACCESS_VIOLATION (trace and stackdump follows).
I've never had a problem with this on Win 2000.
It's not as clear cut as the subject implies though. After the install is
finished, I mv /etc/passwd to /etc/passwd.save, /etc/group to /etc/group.save,
and cygrunsrv still happily succeeds. I brought up another cmd prompt via
Shift+F10 right before executing cygrunsrv, and that too succeeded happily.
I also tried running it through "at" (so that it ran as SYSTEM), and it worked
fine.
The only time I've been able to reproduce this is during an unattended install.
Is this expected behavior?
This is using cygrunsrv-0.95-1.
