The main disadvantage is the increased memory footprint which you have to pay for a flexibility on the target which is usually not necessary. Your (a) is not really an argument; there are several solutions for this "problem", for example: genext2fs - ext2 filesystem generator for embedded systems see http://packages.debian.org/unstable/admin/genext2fs.html gBootRoot - distribution creation program which may be used by a normal user see http://gbootroot.sourceforge.net/ (b) is a matter of taste; for embedded systems, I tend to prefer a fixed, static configuration which does not cost too much of the resources which may be somewhat limited (espacially ROM and RAM).

Some companies call their prototypes "releases", that's all. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
