[Andy Whitcroft]

@hakuna_matata -- thanks for the report there, testing here confirms
your findings that they are upper case on NTFS and only match with upper
case.  Properly the fix for this whole mess should be in util-linux in
blkid as the individual formats have specific forms and only it knows
what is appropriate to do to that UUID such that we do not lose
information in the transformation.  I am filing a new bug for that
isssue so we track it clearly.  See Bug #1553107.

[Touch-packages] [Bug 1548120] Re: [xenial][initramfs-tools] support uppercase and lowercase uuids

[hakuna_matata]

The fix doesn't work for UUIDs of a Windows file system. blkid uses
always UUIDs in upper case for these file systems. So it fails because
the fix converts all UUIDs in lower case.

IMHO short UUIDs (length <= 16) should be always converted in upper case
because short UUIDs are only UUIDs of a Windows file systems.

It can affect also systems without Windows because the EFI partition has
a Windows file system (vfat).

In my case it fails booting into a loopback device(ext4) on a Windows
file system (ntfs).

Please fix your patch. Thanks.

[Touch-packages] [Bug 1548120] Re: [xenial][initramfs-tools] support uppercase and lowercase uuids

[Andy Whitcroft]

Ok, it seems that busybox tr does not actually support symbolic ranges.
Rather than add a first user of awk it seems simpler to manually expand
the character ranges.  Specifically as the specification says the
following:

"The hexadecimal values "a" through "f" are output as lower case
characters and are case insensitive on input."

we can simply map A-F to a-f and cover all valid cases.

@manjo -- I have uploaded this fix to my ppa:apw/ubuntu/initramfs-tools-
test for testing.  Could you do one final test with that one before I
break the archive again.

Hmm, that on the surface of things makes no sense as mini-tr exists in
busybox and in theory at least supports those constructs.  Blocking this
in proposed while we get to the bottom of this.

tr trick does not work in the initramfs environement.

(initramfs) echo "81780AD9-068C-4A80-A795-56856973B8F9" |  cut -f 2 -d = | tr '[
:upper:]' '[:lower:]'

81780AD9-068C-4A80-A795-56856973B8F9


But awk works:
(initramfs) echo "81780ad9-068c-4a80-a795-56856973b8f9" | awk '{print 
tolower($0)}'

81780ad9-068c-4a80-a795-56856973b8f9

I will resubmit the patch using awk instead.

[Touch-packages] [Bug 1548120] Re: [xenial][initramfs-tools] support uppercase and lowercase uuids

[Manoj Iyer]

This patch fixes this issue. I tested the functionality of this function
by creating a script invoking this function as standalone.

$ sudo ./test.sh 
+ resolve_device PARTUUID=275f782b-3c55-4b3f-acb2-c17db0eaee8d
+ DEV=PARTUUID=275f782b-3c55-4b3f-acb2-c17db0eaee8d
+ case "$DEV" in
+ case "$DEV" in
++ echo PARTUUID=275f782b-3c55-4b3f-acb2-c17db0eaee8d
++ cut -f 1 -d =
+ local type=PARTUUID
++ echo PARTUUID=275f782b-3c55-4b3f-acb2-c17db0eaee8d
++ tr '[:upper:]' '[:lower:]'
++ cut -f 2 -d =
+ local value=275f782b-3c55-4b3f-acb2-c17db0eaee8d
+ DEV=PARTUUID=275f782b-3c55-4b3f-acb2-c17db0eaee8d
+ command -v blkid
++ blkid -l -t PARTUUID=275f782b-3c55-4b3f-acb2-c17db0eaee8d -o device
+ DEV=/dev/sda2
+ '[' -e /dev/sda2 ']'
+ echo /dev/sda2
/dev/sda2
+ resolve_device PARTUUID=275F782B-3C55-4B3F-ACB2-C17DB0EAEE8D
+ DEV=PARTUUID=275F782B-3C55-4B3F-ACB2-C17DB0EAEE8D
+ case "$DEV" in
+ case "$DEV" in
++ echo PARTUUID=275F782B-3C55-4B3F-ACB2-C17DB0EAEE8D
++ cut -f 1 -d =
+ local type=PARTUUID
++ echo PARTUUID=275F782B-3C55-4B3F-ACB2-C17DB0EAEE8D
++ cut -f 2 -d =
++ tr '[:upper:]' '[:lower:]'
