I agree that having possibility to take a look at man pages is essential, but I think if it is necessary to have man pages available in AI environment. The assumption might be that when people play with AI, they already have other and also maybe more convenient possibilities where/how they could take a look and inspect documentation (e.g. on AI server or different machine installed with Solaris). That said, I am making that assumption mostly based on my own experiences, so there might be scenarios, where this is not correct. > >> I have created sorted list of packages we have >> in AI Distro Constructor manifest after Dave's >> reduction (list is attached). >> >> After taking a quick look, I can think at least >> following packages could be removed (but I have to >> verify): >> >> 10.66 MB SUNWsfinf GNU and open source info pages > > Possibly removable, though keep comments above in mind.

You are right - I have taken a look at AI proto area and SUNWcs requires SUNWgccruntime, so it will be pulled into AI image. > >> 4.54 MB SUNWgnu-coreutils coreutils - GNU core utilities > > This has a number of utilities which I think are likely to be > desirable to have for debug purposes. I have looked at the content of that package and it seems that it duplicates functionality of other tools already delivered by SUNWcs, SUNWesu(Extended System Utilities) - those we already have in AI image. Some stuff is unique to gnu-coreutils, but I am not sure, what might be really needed: usr/bin/[ usr/bin/base64 usr/bin/dircolors usr/bin/ginstall usr/bin/pinky usr/bin/printenv usr/bin/ptx usr/bin/readlink usr/bin/seq usr/bin/sha1sum usr/bin/sha224sum usr/bin/sha256sum usr/bin/sha384sum usr/bin/sha512sum usr/bin/shred usr/bin/shuf usr/bin/whoami usr/gnu/bin/tsort usr/gnu/bin/whoami > >> 1.85 MB SUNWpkgcmds SVr4 packaging commands > > Needed for adding drivers distributed in SVR4 format, at least.

You are right. But I think we don't need that functionality in AI image, if it is utilized only by IPS server side. I would remove it from the list - in case SUNWipkg allows in future installation only of client part. Thank you very much for your comments !
