Red Hat Enterprise Linux release 8.9 (Ootpa)
lorax-28.14.70-1.el8.x86_64

I'm encountering the following issue which applies to livemedia-creator --make-iso and --make-pxe-live. Reproducible on CentOS Stream 8:
livemedia.log

ERROR Problem zeroing free blocks of /root/.../lmc-disk-zrjj0mv5.img
ERROR pylorax: squashfs.img creation failed
ERROR livemedia-creator: squashfs.img creation failed

program.log

Running... /usr/sbin/fsck.ext4 -y -f -E discard /root/Documents/Documents/results_novirt_2404111703/lmc-disk-zrjj0mv5.img
e2fsck 1.45.6 (20-Mar-2020)
/root/Documents/Documents/results_novirt_2404111703/lmc-disk-zrjj0mv5.img is mounted.
e2fsck: Cannot continue, aborting.


Return code: 8

Command I ran:
livemedia-creator --make-iso --nomacboot --ks rhel8-simple.ks --no-virt --resultdir ./results_novirt_$(date +%y%m%d%H%M)
rhel8-simple.ks

Some more insight on the issue. Appears the filesystem image is not properly unmounted prior to it's execution. Here's the cli output on another attempt for --make-pxe-live option:

Please file RHEL issues at https://issues.redhat.com

FWIW on first glance this looks odd, results_novirt_2404111755/lmc-disk-fzhkyrod.img on /run/media/root/Anaconda makes me wonder if something is automounting it for some reason. lmc does not use /run/media/ for anything. Maybe try not passing ``-resultdirand let it make a temporary directory in/var/tmp`.

(but please followup after filing an issue, not here.
