...ns an array containing consecutive stat structs (not pointers). Changing the return type of guestfs_stat would break API. Changing the generator to support symbol versioning is judged to be too intrusive. Therefore this adds a new struct (guestfs_statns) and new APIs: guestfs_statns guestfs_lstatns guestfs_lstatnslist which return the new struct (or array of structs in the last case). The old APIs may of course still be used, forever, but are deprecated and shouldn't be used in new programs. Because virt tools are compiled with -DGUESTFS_WARN_DEPRECATED=1, I have updated all the plac...

For v3 I reimplemented this using mke2fs -d. This obviously makes the implementation a whole lot simpler, but cannot support multiple directory merging. Patches 1-3 are the same as before. I've also reproduced the notes from v2 below. v2: - Fix inconsistent tab/space. - All 3 plugins now contain a block of text pointing to the other 2 plugins. - TMDIR -> TMPDIR - Unlink the

Another interesting thing you can do with this plugin: https://rwmj.wordpress.com/2019/02/19/nbdkit-linuxdisk-plugin/ v2: - Fix inconsistent tab/space. - All 3 plugins now contain a block of text pointing to the other 2 plugins. - TMDIR -> TMPDIR - Unlink the temporary file and other cleanups along error paths. - fclose -> pclose, and check the return value for errors. -

Turns out Japanese trains are good for coding! In supermin we have a bunch of code to create the libguestfs appliance. It creates it directly using libext2fs (part of e2fsprogs). We can use the same technique to create ext2 virtual disks in nbdkit, which is what this new plugin does. Why a new plugin instead of modifying the floppy plugin? See the 4/4 commit message for an explanation. The

Very large but mechanical change to the generator. Rich.

Split up the huge generator/actions.ml into several smaller files. Rich.

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.
