mkrescue gives error (bug?)

GNU/Linux · 11-06-2013, 02:00 PM

Code:

root@darkstar# mkrescue --iso
mkdir: cannot create directory '/tmp/mkrescue.XXXX0tioxs': File exists
Could not create temporary directory.

Commenting out the following block (in /usr/sbin/mkrescue script) gets rid of the issue (and I get rescue.iso in pwd), as suggested in this Debian bug report

Code:

# mkdir $tmpbase || {
#    echo "Could not create temporary directory."
#    exit 1
# }

Is this solution ok?

Something must be wrong on your computer with regard to creating temporary directories with mktemp. I ran "mkrescue --iso" multiple times. However, later on in the process, the ISO creation falls flat on its nose anyway:

I do not know if Slackware ever had a "genisoimage" program. It does not have one in 13.37 and newer releases.

I'm running Slackware 14, with 3.2.45-smp. mkrescue version 3.2.

Quoting from Debian bug link:

Quote:

the earlier line
tmpbase="`mktemp -dt $(basename $0).XXXXXXXXXX`" || exit

would have already created the directory if there were no errors, correct?

So later in the script when it tries to create the same directory again, we get the error (post 1). Commenting this block would get rid of the error.

Hmm, Looks like the use of genisoimage is new to the mkrescue/lilo version in current

GNU/Linux: You're absolutely right, you've found a bug in lilo as shipped in Slackware 14.0. Your change is OK but I've improved it a bit to make it more informative. The patch below fixes:

lilo-23.2-mkrescue-fix.diff

Also, in so doing, you've revealed an issue in Slackware-current's mkrescue. It now invokes genisoimage from cdrkit (a Debian fork of cdrtools) rather than mkisofs. The patch below makes it Slackware-compatible:

lilo-24.0-mkrescue-fix.diff

Thanks for this report; two birds with one stone.

I never heard back from the OP on this and I've seen no bug-fix patches for lilo on 14.0 or 14.1 so it seems the thread didn't percolate up to Pat.

If "mkrescue" is relatively esoteric then it probably doesn't matter, otherwise someone might want to send smoke signals to the appropriate people.
