mkksiso fails due to operation on an read-only filesystem

[apollo13]

I currently get the following error when running mkksiso using rpms generated from the latest master. My operating system is Fedora 31:

Thanks, looks like I need to just make a copy of everything instead of trying to use the source iso for parts of it.

[apollo13]

Yeah, the graft list contained one file from the original iso. I fixed it locally by just skipping errors during deletion, but I do not know if that is the proper fix. Let me know if you need more details or when I should test a fixed commit.

@apollo13 does commit 95fd12e1f0847950a2a7049d179bf6a42982c72c fix mkksiso for you?

@bcl Jupp, thank you very much!
