(With 512 MB of memory allocated, the update seemed to hang on the glibc update. Boosting the memory to 1024 revealed the above failure.)
* The installation fails as of 27 June 2010 testing with 32-bit Fedora-14 while updating to glibc-common-2.12.90-3.i686
*: Using {{Code|dmsetup status}} the overlay consumption measured (after rebooting from a hang with 512 MB of memory) moved from 23376/409600 to 406568/409600 sectors.
* Installed Fedora-14 soas-i386-20100613.15.iso with this command line,
*: {{Code|/LiveOS/livecd-iso-to-disk --overlay-size-mb 1000 --home-size-mb 200 --delete-home --unencrypted-home /dev/live /dev/sda1}}
*: {{Code|dmsetup status}} before and after
*: {{Code|yum install dkms gcc}}
*: yielded these results: 21376/2048000 and 868152/2048000 (512-byte segments)
*:: So it looks like at least 425 MiBytes of overlay is required for that installation.
*: After
*: {{Code|./VboxLinuxAdditions-x86.run}}
*: {{Code|dmsetup status}} showed 928872/204800 or 454 MiBytes of the overlay consumed.
