Comment(by mikus):

 On the XO-1, I __have__ to 'umount /var/cache/yum' -- because on a 1 GB
 machine the default tmpfs size is 114 MB, which is not enough if yum were
 to decide to download package content data as well as package name data.

 On the XO-1.5, it is my personal choice to 'umount /var/cache/yum'.  [On a
 4 GB machine, the default tmpfs size is 474 MB - which in my opinion is
 plenty.  On a 2 GB machine, having a tmpfs for /var/cache/yum could get
 sticky -- for *really* large yum installs.]  For me, the convenience of
 NOT having to often download all the repository indexes (to repopulate an
 empty tmpfs) outweighs the "loss" of root filesystem space on the internal
 SD card.  [Besides, the typical /var/cache/yum size on my XO-1.5 is 80 MB
 (for nine repositories accessed).]

 [Note:  I have been involved with this situation for a long time, and have
 written tickets to Fedora (fixed) and Sugar (not fixed in 0.84) regarding
 my experiences on the XO with yum install.]

 If you do have /var/cache/yum on the XO-1.5 internal SD card, you can use
 'yum clean' after 'yum install', to minimize the amount of "disk" space
 the yum stuff takes.
