SUMMARY: Unable to install SUNWmdr and SUNWmdu on jumpstart

[goninzo]

So, I've been battling Jumpstart. It's Solaris' method of installing a mass group of clients. I found out the low level problem, and I'm sure there's a high level solution, but here is my low level solution. I'll update it if someone can give me a better solution rather than hacking the packages themselves. Sorry if I go into technical detail

You know, your problem with Jumpstart is one of the reasons I refused to use Unix in any of its incarnations for my entire working life. Anything that sits there and dares you do do something right, should be exorcised, burned at the stake, and all of its male children gelded.

Oh it's great when it's working right. It's just difficult to deal with, and I'm adept at dealing with it's idiosyncrasies.

UNIX is user friendly. But it's just very particular about who it's friends are.

(Found you from /.)

I suggest pointing truss at the shell running the script with '<<' in it, and watch for where it tries to create a file in /tmp with open() or creat(). See what return code you get. I would be on /tmp/ being on a full filesystem if I got that error, but I'd guess you've checked that. :-)

[goninzo]

Yeah, um it's somewhat hard because it's forked off of the shell, and if I trace forks, and I'm on a shell that I'm running the truss, I get a trace off of the truss I'm running... yeah bad.

And I can do an echo bob >/tmp/bob fine, but a cat >bob <

[gwillen]

Hrm. So I can do (this is on Linux but I assume will work with truss also, substitute for -f whatever your follow-fork-flag is)

strace -f sh -c 'cat >bob <
And I can see it making the open(...) call on a file in /tmp/.

Wow I spent a few weeks writing software this year that would make your life easier but I can't write about it so much. I'm mysteriously near-useful like that :P
