I'm management a server that in
/etc/fstab have references to some partitions using
The server suddenly power-off and DISK_ID part of
I always refer partition in
/etc/fstab using UUID and will change the conf of fstab, but still I want know why the by-id change when tons of people on Internet said that such hard disk identifier don't change, even I read that OpenSuse use by-id in tis fstab.
Can partitions *UUID*s change too after a suddenly power-off? are *UUID*s less "mutable" than *by-id*s? I think that an explanation from where by-id come will help me to understand all this. I read that UUID is stored in the partition and just change its value after partition formatting, but not know much about by-id, just that udev is who generated-create it, but basing in what?
