This sounds reasonable. The EeePC is not a distro, it is a brand of netbook
with two SSD drives, an 8 GB (on which I have installed '/' and '/boot') and
a 32 GB (on which I have '/home'). The distro is ubuntu 9.04. It comes with
1 GB RAM, so I split the 4 GB SDHC into two partitions, sdc1 being the
shrunken fat32 fs, and sdc2 being swap.
I followed Casey's advice with fstab and added the following lines:
# swap is /dev/sdc2 (SDHC card)
UUID=41d27b10-5a3f-4523-b170-08542387c830 none swap sw 0 0
# /mnt/extra is on SDHC card
UUID=72AD-2013 /mnt/extra vfat relatime 0 2
I used uuid instead of /dev/sdc# so as to avoid confusion with other removable
media that may wish to become sdc.
Is there a way, with your init script, to handle sdc1 and take advantage of
uuid?
