Re: [Dvdrtools-users] mkisofs - no largefile support for files inside UDF isos?

[Andre Dalle]

Well, a fair question - but XFS was designed to handle large files and
filesystems.

This should be evidenced by the fact that I *do* have ISO images greater than
2GB on my disk.  Currently 4 ~2.5GB, 2 ~3.4GB, and 1 ~4.2GB.

And, after all, I can create large ISOs with mkisofs - the support is there,
but it seems to reject individual files larger than 2GB for adding into an
ISO.

Have you, or others, succeeded in creating ISOs with files larger than 2GB in
them?

At least, I can know whether what I'm attempting to do has been done before.

If noone can confirm this... then I may peek at the mkisofs code and see if
largefile support is somehow incomplete.
