Why even ask the question - if you know what you are doing you can
change it later on.
What if you don't know what you're doing, but simply do not want the newly
introduced feature X for whatever reason?
We don't go around asking
Preferred Emailer
What inode size should we use on ext3 Adjust raid readahead
so why ask about what to most users are internal details about how we
make sure their data reappears next reboot ?
Where do you draw the line? Is "which ports do you want to open in the
firewall" less technical? Is creating custom partitions less technical?
How about package selection? We do have a choice there (for now).
Incidentally and for my own understanding: I am able to mount/umount
/dev/sdaX and such, if I wanted to, so the system can and does know the
partitions by labels. Why do I have to see the UUID garbage in /etc/fstab
though? This is not a rant, it's an actual question.
The system does not know partitions by label. Partitions don't have
labels (unless they're elements of an md array and have something in the
superblock). Partitions have device names, but they can change, drives
are named by the order of detection. So you can't always count on the
device name.
Filesystems have labels, and unlike partition device names or UUIDs,
they need not be unique, so two installs on different drives or
partitions can leave you with two filesystems names "/".
Only the UUID is (a) not going to change and (b) not going to be
duplicated by anything like normal system operation. It is therefore the
least likely to lead to an unwanted learning experience.
