If by 'fragile' you mean 'does not lobotomize it to the point it'll never work again' then yes, it's fragile, and we are weak-minded cowards for suggesting it. Smilie

By broader standards, well: All it amounts to is an init system, if you're willing to rely on your init scripts to boot the machine you can rely on this to not boot RCP. Comment out the RCP settings and it won't understand how to use RCP any more. It's also the correct way; disabling RCP just by blasting holes in the executables doesn't warn inetd of this, so could cause weird error messages. An attacker would have to modify arbitrary files as root, or induce inetd to run and/or modify arbitrary files as root, in order to kick RCP on; if he could do that you're screwed with or without RCP.

(I don't like inetd either, but because of how complicated it makes everything, not any particular security complications. It just runs daemons, the daemons run as per usual.)
