When I mount CDROM, the output from dmesg says:

Max size:328085 Log zone size:2048
First datazone:36 Root inode number 73728
ISO9660 Extensions: RRIP_1991A

It means that the format of the mounted disk is ISO9660 with Rock
Ridge Interchange Protocol (= long file name, uid, gid, etc.) enabled.
I think Linux kernel automatically detect and enable Rock Ridge
Extension and translate file names, etc.

The /dev/sda1 you mentioned is created with Rock Ridge Extension?
Does mkisofs can create Rock Ridge Extension format ?
