To improve performances or avoid disk i/o, one may mount /tmp in memory (mfs). As example to create a /tmp using 10% of available RAM:
|
|
</p>
|
|
<pre>
|
|
# sed -i '/\/tmp /s/^/\#/' /etc/fstab
|
|
# printf "swap /tmp mfs rw,nodev,nosuid,-s=%sB 0 0\n" \
|
|
$(dmesg |awk '/avail mem/ { print $4 }') \
|
|
>> /etc/fstab
|
|
# chmod 1777 /tmp
|
|
# mount -a
|
|
</pre>
