Strange genisoimage result

[Paolo Galtieri]

I was using genisoimage to create a backup iso image.  The contents of the
directory I backed up are as follows:

total 4234022
-rwxrwxrwx. 1 pgaltieri pgaltieri        221 2010-01-01 08:10 excludes
-rwxrwxrwx. 1 pgaltieri pgaltieri 4318858312 2010-01-01 08:36 files.tgz
-rwxrwxrwx. 1 pgaltieri pgaltieri   12992359 2010-01-01 08:11 flist
-rwxrwxrwx. 1 pgaltieri pgaltieri    3784365 2010-01-01 08:11 fprops
-rwxrwxrwx. 1 pgaltieri pgaltieri        560 2010-01-01 08:10 partitions
-rwxrwxrwx. 1 pgaltieri pgaltieri          4 2010-01-01 08:36 ver

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:

-r--r--r--. 1 4294967295 4294967295        221 2010-01-01 08:10 excludes
-r--r--r--. 1 4294967295 4294967295 4318858312 2010-01-01 08:36 files.tgz
-r--r--r--. 1 4294967295 4294967295   12992359 2010-01-01 08:11 flist
-r--r--r--. 1 4294967295 4294967295    3784365 2010-01-01 08:11 fprops
-r--r--r--. 1 4294967295 4294967295        560 2010-01-01 08:10 partitions
-r--r--r--. 1 4294967295 4294967295          4 2010-01-01 08:36 ver

Notice the strange user and group ids.  I backed up another directory

total 2055002
-rwxrwxrwx. 2 pgaltieri pgaltieri   3344047 2009-11-25 22:53 259313 All
code.zip
-rwxrwxrwx. 2 pgaltieri pgaltieri    403648 2009-11-25 22:55 9780470525937
Entire Book Download.zip
-rwxrwxrwx. 2 pgaltieri pgaltieri 342437920 2009-11-12 17:16
AcroPro90_efg.exe
-rwxrwxrwx. 2 pgaltieri pgaltieri  27386280 2009-11-24 22:06
AdbeRdr920_en_US.exe
-rwxrwxrwx. 2 pgaltieri pgaltieri      2381 2009-09-08 17:22 Advanced Subnet
Calculator.lnk
.
.
.

and after generating the iso image and mounting it loopback it shows:

[root at peglaptop ~]# ll /mnt/loop
total 2054932
-r-xr-xr-x. 1 root root   3344047 2009-11-25 22:53 259313_a.zip
-r-xr-xr-x. 1 root root    403648 2009-11-25 22:55 97804705.zip
-r-xr-xr-x. 1 root root 342437920 2009-11-12 17:16 acropro9.exe
-r-xr-xr-x. 1 root root  27386280 2009-11-24 22:06 adberdr9.exe
-r-xr-xr-x. 1 root root      2381 2009-09-08 17:22 advanced.lnk
-r-xr-xr-x. 1 root root    251840 2010-01-11 12:40 b2cappse.exe
.
.
.

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?
