/var/log in eine RAMDisk auslagern:

In die /etc/fstab schreiben:

tmpfs /var/log tmpfs defaults,noatime,nosuid,mode=0755,size=50M 0 0

Jetzt noch das varlog-Script aus diesem Thread umsetzen! (Siehe Dateianhänge an dieser Seite)

cat >> /etc/logrotate_varlog.conf << "EOFCONF"
# see "man logrotate" for details
# rotate log files weekly
#daily

# keep 4 weeks worth of backlogs
rotate 7

# create new (empty) log files after rotating old ones
create

# uncomment this if you want your log files compressed
compress

# Logs are moved into directory for rotation
olddir /var/archive

# packages drop log rotation information into this directory
#include /etc/logrotate.d
