[Voyage-linux] [BUG REPORT] voyage-0.2pre4: DHCP client could not write to /var/run/

[Leon Woestenberg]

Hello,

I wanted to report a bug that I have found during my PXE/NFS tests (on 
WRAP.2C using voyage-0.2pre4 on CF disk).

The DHCP client does not seem to have write access to "/var/run" when is 
gets its lease. Consequently, there is not PID or leases file in this 
directory.

After the DHCP lease runs out of time, the interface brought down! The 
lease time at my personal setup is five minutes, but usually it is much 
longer than that (one day, one week) before the lease runs out and you 
notice this bug.

I am pinpointing where this goes wrong, but maybe someone else can look 
along? My weekend is nearly ending :-)

Regards,

Leon.
