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: [r...@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? Paolo
