Re: Announcing mkisofs 1.13

Hi,

> * Support for creating large images (> 4 GiB).

You are aware that even quite young Linux kernels
have problems to read multi-extent files ?
My 2.6.18 swallows the last few bytes if the file
size is not a multiple of 2048.
(libisofs can dare to produce such files without
 warning because itself is able to extract them
 out of ISO images, if the kernel cannot.)

Do you have experience with El Torito pointing
to something other than ISOLINUX ?
(Nothing against ISOLINUX. I just wonder whether
 there are other El Torito bootable systems and
 how to bring them into an ISO image.)


> * Support for embedding bootloader code for disk boot on PC/BIOS platforms

Do you have specs for that ?
libisofs does the isohybrid MBR trick of
ISOLINUX but cannot install MBRs in general.
(The question is about how one has to patch
 the boot image and/or the MBR after the block
 address of the boot image is determined.)


Oh well, i hoped for allies in a session oriented
UDF endeavor. Proper multi-session, so that not
can happen what happened to the backup of Zhang
Weiwu. (First session UDF+ISO, second ISO, mount
gets confused.)

Do you have plans for UDF ?
(Problem seems to develop a proper model of how
 the components of ECMA-167 form an UDF compliant
 graph that implements multi-session.)


Have a nice day :)
