Description Mark B. Allan 2000-10-03 22:05:35 UTC

Using LABEL: in fstab instead of a /dev/hd* entry is a very bad idea
because many people (myself included) have several Linux installs on the
same machine. When I do an upgrade, I keep the old version and install the
new version on different partitions (keeping only /home and /usr/local) so
I can go back to the old OS if necessary. What happens when there are two
or three partitions with the label "/usr"?

Comment 1 Erik Troan 2000-10-05 13:03:43 UTC

The install checks all type 0x83 partitions for labels to make sure that it is
using unique labels. If a / already exists, for example, the new / will be
label'd /1. Similiar changes happen for /usr, and to avoid
/usr/share/something/or/other and /usr/share/something/or/this from having
the same label after being truncated to fit in the superblock. Yes, this has all
been tested ;-)
