mounts same filesystems over and over

[Tormod Volden]

Binary package hint: casper

When scripts/casper is looking for the CD root, it goes in a loop checking all partitions it can find from the block devices and mounts the partition to check if the filesystem contains the CD root. Until the CD is found, it does the whole search over again. For instance if you have a slow device for the CD root, every ext* filesystem on your hard drive is continuosly mounted and remounted again for quite some time (60 times if the CD is missing). This explodes the mount count and you have to fsck your filesystems unnecessarily.

Observed behaviour: File systems that have been mounted and checked are checked again for no good reason

Expected behaviour: Only mount filesystems that have not been verified before.

I suggest running a tab of UUID's from the verified filesystems. Of course, we want to recheck any partition names that can change contents because devices might be hotplugged, but for a filesystem already identified by UUID we can check once and expect it to not change contents during boot.
