/dev/root / ext3 rw,data=journal 0 0
/dev/VolGrp0/usr /usr ext3 rw,nodev,data=journal 0 0
/dev/VolGrp0/var /var ext3 rw,nodev,data=journal 0 0
/dev/VolGrp0/squid_spool /var/cache/squid/cd0 ext3 rw,nosuid,nodev,noatime,data=writeback 0 0
/dev/VolGrp0/squid_spool2 /var/cache/squid/cd1 ext3 rw,nosuid,nodev,noatime,data=writeback 0 0
/dev/VolGrp0/news_spool /var/spool/news ext3 rw,nosuid,nodev,noatime,data=ordered 0 0
