which ext# format to use on /opt usb drive?

yamon3 wants ext4

diversion wants ext2

compromise with ext3 ?

make 2 separate partitions ?

so what's a boy to do

 

Use any of these. They are just recommendations, not requirements.

 

I suggest ext4 with journalling disabled.

Note: in examples below my target partition was sda1, yours may differ.

To format ext4 no journal:

Code:

mke2fs -t ext4 -O ^has_journal /dev/sda1

To relabel the drive:

Code:

tune2fs -L "myusbdrive" /dev/sda1
