[Voyage-linux] Shutdown and hwclock writing on RO filesytem

[Teco Boot]

During shutdown, the following message appears:

Saving the system clock.
hwclock: Could not open file with the clock adjustment parameters in it
(/etc/adjtime) for writing, errno=30: Read-only file system.
Drift adjustment parameters not updated.

Tested on daily build, date 19jan2010. 
I'm not sure /etc/adjtime being written is useful.
My Alix devices haven't battery backup clock, but I reboot from time to
time.

And is hwclock --adjust performed every now and then?
Useful?

Regards, Teco
