UUID confusion revisited

[Alan E. Davis]

Thank you for this script.  It shows me some things that are
troubling, at the least.  It would be nice if the output were labelled
with  a header.  Meanwhile, do you mind to  take at look at this
output?  The lines are wrapped badly.  Note sda1, sda2, sda5 (which
prints out two UUIds that are the same!), and sda6.


aed at electrolux:~$ sh ./uuidcompare.sh
sda1 UUID=357420c4-68ca-4206-b7ad-fec6bbfabd56
UUID=af948971-8091-4105-85f0-   c471ab886fc8
sda2 UUID=b652dea8-5619-40ae-ae48-d6d3ced98264
UUID=8823e2d6-e44b-478f-a54d-c59887ef9637
sda3 UUID=c8a7e68d-5688-453e-9fae-dd8315358111
sda5 UUID=862cf3f9-f23e-4ba4-94b8-98e718b51572
UUID=862cf3f9-f23e-4ba4-94b8-98e718b51572
sda6 UUID=f6175525-5ff4-44e7-ab35-9bac7ae7ec2a
UUID=3cf06617-cbb8-4043-a5a8-1f5db420d748
sda7 UUID=c7a3c324-b660-4acc-8ace-d59cef7bdc8b
sda8 UUID=b24c270c-445d-4843-8dc6-b5dcc22195e7
sdb1 UUID=af948971-8091-4105-85f0-c471ab886fc8
sdb2 UUID=8823e2d6-e44b-478f-a54d-c59887ef9637
sdb5 UUID=00b7db1e-109d-4787-9abf-fc114d341566
sdb6 UUID=3cf06617-cbb8-4043-a5a8-1f5db420d748

I swear when I ran this script 15 minutes ago, only two filesystems
printed out double UUIDs.

Any comments or suggestions?  By the way, /dev/sda5 and sdb5 are a
real problem.  I have and IDE drive and a SATA drive.  The partitions
are reassigned at some point during boot after the actual /dev/sda5
(SATA) has been mounted as swap: the fsck stops at sda5 and says it's
already mounted.

I have the opinion there are other issues at odds that are not
reflected in /etc/fstab or df or the listing of /dev/disk/by-uuid.

I am losing hair at a higher than normal rate.

Alan
