[sf-lug] Chromebooks' partitioning optimizing

[aaronco36 at sdf.org]

A good way to deal w/ the Chromebooks' low HW specs is to use SD cards
in their SD slots to increase their available internal diskspace.
Already wrote to Bobbie abt this the last time.
E.g. w/ 32 GB microSD card /dev/mmcblk1p
1) 4 GB swap-part
2) 4 GB /var
3) 4 GB /usr/local
4) Remaining space as Ext'd for MBR BIOS
5) 1 GB /tmp
6) 16 GB+ /home

--> After creating and partitioning /dev/mmcblk1p3 as /usr/local ....
then create /usr/local/opt and symlink /opt to /usr/local/opt
( 'sudo cp -v /opt /usr/local/opt ; sudo ln -sf /opt /usr/local/opt' )

The Chromebooks' default internal 16.0 GB /dev/mmcblk0p as
1) ~300 MB EFI boot (efs)
2) 14 GB+ /<root>
( swap on (2) as 2 GB swap _file_ )
