+Supermin appliance to febootstrap
+---------------------------------
+
+Supermin appliance functionality should be moved into febootstrap.
+
+Ideas for extra commands
+------------------------
+
+ General glibc / core programs:
+ chgrp
+ grep (do it locally using pipe?)
+ dd (?)
+ ln / ln -s
+ readlink
+ utime / utimes / futimes / futimens / l..
+ more mk*temp calls
+ some sort of alloc/fallocate/posix_fallocate call to create empty space
+ realpath
+ trunc[ate??]
+
+ ext2 properties:
+ chattr
+ lsattr
+ badblocks
+ blkid
+ debugfs
+ dumpe2fs
+ e2image
+ e2undo
+ filefrag
+ findfs
+ logsave
+ mklost+found
+
+ SELinux:
+ chcat
+ restorecon
+ ch???
+
+ Oddball:
+ pivot_root
+ fts(3) / ftw(3)
+
+Swap space
+----------
+
+Allow swap space from the guest to be used. Is it a good idea?
+
+Query guest architecture
+------------------------
+
+Need a way to query a binary or library file for its architecture.
+Using objdump or readelf?
+What about non-ELF files (eg. Windows, BSD).
+
+To do this properly requires some serious logic, eg. to cover Linux
+and Windows we'd need objdump and i686-pc-mingw32-objdump, and more to
+cover a.out, COFF and 64 bit Windows. Therefore this cannot be done
+inside the daemon, and should be done by a separate, external program
+similar to virt-inspector.
+
+Probably we should go all the way and have virt-inspector able to
+determine kernel and userspace architectures of guests.
+
+Other initrd-* commands
+-----------------------
+
+Such as:
+
+initrd-extract
+initrd-replace
+
+Simple editing of configuration files
+-------------------------------------
+
+Some easy non-Augeas methods to edit configuration files.
+I'm thinking:
+
+ replace /etc/file key value
+
+which would look in /etc/file for any instances of
+
+ key=...
+ key ...
+ key:...
+
+and replace them with
+
+ key=value
+ key value
+ key:value
+
+That would solve about 50% of reconfiguration needs, and for the
+rest you'd use Augeas, 'download'+'upload' or 'edit'.
+
+RWMJ: I had a go at implementing this, but it's quite error-prone to
+do this sort of editing inside the C-based daemon code. It's far
+better to do it with Augeas, or else to use an external language like
+Perl.
+
+Quick Perl scripts
+------------------
+
+Currently we can't do Perl "one-liners". ie. The current syntax for
+any short Perl one-liner would be:
+
+ perl -MSys::Guestfs -e '$g = Sys::Guestfs->new(); $g->add_drive ("foo"); $g->launch; $g->wait_ready; $g->mount ("/dev/sda1", "/"); ....'
+
+You can see we're well beyond a single line just getting to the point
+of adding drives and mounting.
+
+First suggestion:
+
+ $h = create ($filename, \"/dev/sda1\" => \"/\");
+
+ $h = create ([$file1, $file2], \"/dev/sda1\" => \"/\");
+
+To mount read-only, add C<ro =E<gt> 1> like this:
+
+ $h = create ($filename, \"/dev/sda1\" => \"/\", ro => 1);
+
+which is equivalent to the following sequence of calls:
+
+ $h = Sys::Guestfs->new ();
+ $h->set_autosync (1);
+ $h->add_drive_ro ($filename);
+ $h->launch ();
+ $h->wait_ready ();
+ $h->mount_ro (\"/dev/sda1\", \"/\");
