@ygemici:
Thanks for the input.
As mentioned in the output from genisoimage, the file which commonly gets written to is isolinux.bin,
Quote:
genisoimage: Read-only file system. Error opening boot image file './isolinux/isolinux.bin' for update.
...although there might be others in certain instances (comments, anyone?)
BTW: The original citations were taken from the OP found in this
serverfault thread. I was able to reproduce the output on my (offline) "distro-maker" using a similar commandline with the sourcefile partition set as read-only. If allowed, genisoimage will definitely do as it indicates; and the target sourcefile (isolinux.bin) will be altered.
There doesn't seem to be any help in the manpages regarding a commandline parameter which would suppress this behavior. Which of your above commandline parameter(s) might work to keep these writebacks from occurring? Is the entire string to be utilized as a kind of "panacea"???
In any event, it seems as though this is a widely-applicable issue; and, judging from the number of hits this thread had in just the first 24 hours (over 5K), I'm not the only one out here with some concern...
Anyone else seen this?
Thanks
