Description James Laska 2010-10-13 11:26:51 EDT
Description of problem:

Plymouth used to only prompt for a passphrase once, and attempt to use that for all subsequent encrypted devices.  As of F-14-TC1, it appears that plymouth prompts for a passphrase for each encrypted device.  This is specific to serial console booting.

Version-Release number of selected component (if applicable):

plymouth-0.8.4-0.20100823.4.fc14

Steps to Reproduce:
1. Combine the following two tests
  * https://fedoraproject.org/wiki/QA:Testcase_Anaconda_User_Interface_serial_console
  * https://fedoraproject.org/wiki/QA:Testcase_Anaconda_autopart_(encrypted)_install
 
Actual results:

Prompted for a passphrase for each of the encrypted devices (tested 2 and 4)

Expected results:

Prompted only once, regardless of the number of encrypted devices (assuming the same passphrase is used for all devices)

Comment 3 James Laska 2010-10-15 11:06:56 EDT
Moving this back to ASSIGNED.  I don't believe this is resolved with plymouth-0.8.4-0.20100823.5.fc14. 

Discussed with Ray on IRC, and it appears an additional patch may need to be backported into F-14.

10:54:33   jlaska: halfline: I attempted to gather plymouth:debug information to post into the issue, but that just seems to hang on boot (might be sending output elsewhere, dunno)
10:55:09   halfline: jlaska: means plymouth is crashing
10:55:41   halfline: jlaska: if you run wth plymouth:debug and plymouth crashes then it will pause() so you can attach with gdb. should probably only do that if the root fs is mounted i guess...
10:56:17   halfline: jlaska: and just to be sure, you rebuilt the initrd after updating?
10:56:27  * jlaska did a fresh install with 'updates-testing' enabled
10:56:53   jlaska: halfline: so the initrd should have only been created using the latest plymouth
10:57:10   halfline: jlaska: there's some output before it hangs right?
10:57:13   halfline: can you post that output?
10:57:39   jlaska: halfline: http://fpaste.org/9Vym/
10:59:44   halfline: jlaska: sigh, the plymouth in f14 is older than i thought
Comment 4 James Laska 2010-10-15 11:37:30 EDT
Tested plymouth-0.8.4-0.20100823.6.fc14 (http://koji.fedoraproject.org/koji/buildinfo?buildID=200648)

# rpm -q plymouth
plymouth-0.8.4-0.20100823.6.fc14.x86_64

# /usr/libexec/plymouth/plymouth-update-initrd 
# reboot

...

Password for /dev/sdb1 (luks-2b6...):*********

^^^ only prompted one time.  The same passphrase was used for remaining encrypted devices.

Moving back to MODIFIED, pending updated bodhi that contains plymouth-0.8.4-0.20100823.6.fc14
Comment 5 James Laska 2010-10-15 14:19:56 EDT
Easy workaround, enter the passphrase for each time prompted.  However, I'd like to request including this fix in F-14 as it's tested, and sufficiently annoying for folks doing serial-console installations that include encrypted partitions (virt).
