# fix commented out in SVN
thanks

Petter made me aware of constant RAM consumtion by ntpd if  
/var/log/ntpstats is mounted on tmpfs. Searching for another way to  
get rid of syslog floodings...

   Betreff: Bad idea to allow ntpd to write to /var/log/ntpstats/ on  
diskless workstations? (Was: r74218 - in trunk/src/debian-edu-config:  
debian share/ltsp/ltsp_config.d)
        An: debian-edu@lists.debian.org

This is probably a bad idea, as ntpd will fill up this directory with
logs, and thus slowly eat RAM away from the diskless machine.  I decided
to not make this directory writable to avoid it, as ntpd work fine
without write access to this directory.  The only issue is some warnings
from ntpd, and these can be ignored.

Happy hacking,
