Well while 532324 is a perfect example how some developers obviously think they can ignore the policy just as they like (this issue is really unbelievable,... wonder why we have all that policy crap...) in order to save them work... I'd agree that at least section 10.4 of the policy does not mandate that the SUS3 Utilities are available,... as far as I understand it just talks about compliance of shells providing /bin/sh with the SUS3 Shell Command Language (which is not the Utilities),... and IIRC printf is not required to be a built-in... Nevertheless I still think that this stuff has to be there because of the definition of "essential". - Either this on is not exactly formed (so essential means only always installed, but does not mean always available)... but this would make the whole concept rather stupid IMHO,.. because then we'd again have to check for every single essential thing we're using anywhere. - Or it does mean, that everything essential has to be available always,.. which would include at least the time when init takes over from the kernel or the initramfs image. But then we'd have a problem as many packages put their stuff in /usr/ > This is indeed a problem if /bin/sh has no printf builtin, but it does > not affect people who use dash or bash. Well but it's rather ugly to simply say dash/bash support it,.. => we're fine... > So is dpkg, and it lives almost completely under /usr, except for > start-stop-daemon.

Is there any policy document or that like,... which mandates: a) What is guaranteed to be available in initramfs images? b) What is guaranteed to be available as soon as the root-fs is mounted (I mean /etc/, /bin/, /sbin, /lib/,.... but not /usr c) When (!) it is guaranteed that also /usr/ is there? Is it after $remote_fs? Or after mountall-nfs.sh? > Only init scripts that do not depend on $remote_fs have to do this check. There are quite a lot... Cheers, Chris.
