Description Jussi Silvennoinen 2004-12-21 08:55:52 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.3)

Description of problem:
RHEL3 U4 does not boot if /tmp is a symlink to another FS than /.
Tried on one box with U3 -> U4 update and on another with a clean U4
install, using our own kickstart which among other things, symlinks
/tmp to /var/tmp.

During the boot process, I see

Starting up RAID devices: md0 md4 md2 md3 md1
Cannot create temp file /tmp/devlabel.luyk7Al
/sbin/devlabel: line 893: $temp_proc: ambiguous redirect

Looking at the code, I see:

temp_proc=`mktemp /tmp/devlabel.XXXXXX`
echo "$proc_partitions" > $temp_proc

Removing the symlink and creating /tmp with 1777 bits allows normal
booting. Or removing devlabel-package.

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

How reproducible:

Steps to Reproduce:
1. Install RHEL3U4 using our own kickstart
2. Reboot the box


Actual Results:  Boot fails with the last messages on screen:

Starting up RAID devices: md0 md4 md2 md3 md1
Cannot create temp file /tmp/devlabel.luyk7Al
/sbin/devlabel: line 893: $temp_proc: ambiguous redirect

Expected Results:  After starting RAID devices, continue with mounting
filesystems and the rest of the boot process.

Additional info:

U3 devlabel-0.42.05 does not suffer from this.

Use / as the temporary directory if /tmp isn't a directory.

We could also check the retval of mktemp, this version is shorter.

don't use mktemp at all

I prefer this, it certainly seems simpler.
Comment 4 Matt Domsch 2005-01-06 17:50:27 EST
I agree with Bill.  Good cleanup.
I'll see if DKMS has a similar construct it can change also.
Comment 5 Bastien Nocera 2005-01-07 04:18:28 EST
Good work Bill. It's better than my quick fix ;)
