I put it on an 8gb micro SD card because that's all I had.
I bought a new 32gb one (they don't sell 8gb anymore and 32gb was $1 more than 16gb.
My current layout is:
# df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 102.4M 23.4M 76.9M 23% /
tmpfs 460.7M 1.7M 459.0M 0% /tmp
/dev/mmcblk0p1 63.9M 15.7M 48.2M 25% /boot
tmpfs 512.0K 0 512.0K 0% /dev
When I dd it to the 32gb, I will also increase the partition sizes.
Should I just increase the / partition?
Is ext4fs less reliable on larger partitions (eg. is a larger partition more likely to get corrupted by a power failure)?
I plan to try to setup NUT for my UPS.
