I have two netbooting diskless atom based mini itx boards The one with 3GB ram with up to 2.5GB to tmpfs (tmpfs will use up to whats free) and will fail regularly on glibc, gcc and some others. The one with 4gb ram is usually ok. fstab: shm /dev/shm tmpfs nodev,nosuid,noexec 0 0 tmpfs /tmp tmpfs size=2500M,mode=1777,noatime,auto 0 0 tmpfs /var/lock tmpfs size=10m,noatime,auto 0 0 tmpfs /var/run tmpfs size=10m,noatime,auto 0 0 tmpfs /var/cache/hald tmpfs size=10m,noatime,auto 0 0 * note that I am still using a 2.6 kernel.
