I can reproduce this on spacewalk master, directories have incorrect names only inside ISO, in working directory they seem correct.
fixed in spacewalk.git(master): 4e0b275421a2e674c297f94a3b59d30505f8b9da
Reproduced on spacewalk-backend-2.5.3-151.el6sat using the reproducer from the initial report. The bug is triggered only if doing an export to the current directory using "-d ." option. Both following exports are done on spacewalk-backend-2.5.3-151.el6sat. $ rhn-satellite-exporter --channel=rhel-x86_64-server-6 --start-date=20161101 --end-date=20161201 -d preupdate --make-isos=dvd <...> $ mount -o loop preupdate/satellite-isos/rhn-export-20161101000000-20161201000000.0-01.iso /mnt/iso/ $ ls -R /mnt/iso /mnt/iso: arches blacklists channel_families channels DISK_1_OF_1 product_names /mnt/iso/arches: arches-extra.xml.gz arches.xml.gz /mnt/iso/blacklists: blacklists.xml.gz /mnt/iso/channel_families: channel_families.xml.gz /mnt/iso/channels: rhel-x86_64-server-6 /mnt/iso/channels/rhel-x86_64-server-6: channel.xml.gz comps.xml.gz /mnt/iso/product_names: product_names.xml.gz $ cd preupdate $ umount /mnt/iso $ rm -rf * $ rhn-satellite-exporter --channel=rhel-x86_64-server-6 --start-date=20161101 --end-date=20161201 -d . --make-isos=dvd <...> $ mount -o loop satellite-isos/rhn-export-20161101000000-20161201000000.0-01.iso /mnt/iso/ $ ls -R /mnt/iso/ /mnt/iso/: acklists annel_families annels ches DISK_1_OF_1 oduct_names /mnt/iso/acklists: blacklists.xml.gz /mnt/iso/annel_families: channel_families.xml.gz /mnt/iso/annels: rhel-x86_64-server-6 /mnt/iso/annels/rhel-x86_64-server-6: channel.xml.gz comps.xml.gz /mnt/iso/ches: arches-extra.xml.gz arches.xml.gz /mnt/iso/oduct_names: product_names.xml.gz Directory names on the final iso for the export created with "-d preupdate" are ok. Directory names on the final iso for the export created with "-d ." are truncated. Tested "-d /root/satexporter/preupdate/" (absolute path) as well - directory names are ok there. Updated to spacewalk-backend-2.5.3-152.el6sat and ran all the exports again. This time directory names for every type of export (current dir, relative dir, absolute path) were correct and not truncated. VERIFIED
