I just realized this does not work for a modular initramfs, composed at load time from multiple files, which is a very real problem. Should be easy enough to deal with: instead of one large file, use one companion file per source file, perhaps something like filename..xattrs (suggesting double dots to make it less likely to conflict with a "real" file.) No leading dot, as it makes it more likely that archivers will sort them before the file proper. > This version of the patch was changed from the previous one exactly to deal with this case -- > it allows for the bootloader to load multiple initramfs archives, each > with its own .xattr-list file, and to have that work properly. > Could you elaborate on the issue that you see? > Well, for one thing, how do you define "cpio archive", each with its own .xattr-list file? Second, that would seem to depend on the ordering, no, in which case you depend critically on .xattr-list file following the files, which most archivers won't do. Either way it seems cleaner to have this per file; especially if/as it can be done without actually mucking up the format. I need to run, but I'll post a more detailed explanation of what I did in a little bit. -hpa
