I was using genisoimage to create a backup iso image. The contents of the directory I backed up are as follows:<br><br>total 4234022<br>-rwxrwxrwx. 1 pgaltieri pgaltieri 221 2010-01-01 08:10 excludes<br>-rwxrwxrwx. 1 pgaltieri pgaltieri 4318858312 2010-01-01 08:36 files.tgz<br>
-rwxrwxrwx. 1 pgaltieri pgaltieri 12992359 2010-01-01 08:11 flist<br>-rwxrwxrwx. 1 pgaltieri pgaltieri 3784365 2010-01-01 08:11 fprops<br>-rwxrwxrwx. 1 pgaltieri pgaltieri 560 2010-01-01 08:10 partitions<br>-rwxrwxrwx. 1 pgaltieri pgaltieri 4 2010-01-01 08:36 ver<br>
<br>When I tried to back it up it failed initially because the files.tgz was > 4Gb. I reran it with the -allow-limited-size which worked. I mounted the iso image in loopback mode, ran ls -l /mnt/loop and got the following result:<br>

<br>Notice the strange user and group ids. I backed up another directory<br><br>total 2055002<br>-rwxrwxrwx. 2 pgaltieri pgaltieri 3344047 2009-11-25 22:53 259313 All code.zip<br>-rwxrwxrwx. 2 pgaltieri pgaltieri 403648 2009-11-25 22:55 9780470525937 Entire Book Download.zip<br>

.<br>.<br>.<br><br>and after generating the iso image and mounting it loopback it shows:<br><br>[root@peglaptop ~]# ll /mnt/loop<br>total 2054932<br>-r-xr-xr-x. 1 root root 3344047 2009-11-25 22:53 259313_a.zip<br>-r-xr-xr-x. 1 root root 403648 2009-11-25 22:55 97804705.zip<br>

.<br>.<br>.<br><br>In this case the user and group ids were changed from pgaltieri to root. Is the behavior using -allow-limited-size expected behavior or is this a bug in genisoimage?<br><br>Paolo<br><br>
