There are 3 possibilities...
Put the mod commands in a .crashrc file in the current directory,
If it were static, I could. This is for analyzing crash dumps that
have been created on other systems.
Or do it during a crash session by putting the commands in a file,
and run the command's contents by redirecting:
crash> < input
crash> mod -s< input
I gather that both of these are really the same in that the first case
simply appends each input line to an empty string. This is exactly what
I was asking for, plus a little bit. Since I wasn't expecting the
"mod -s < input" formulation, I likely just didn't stumble over it.
Anyway, since I won't know in advance which modules are loaded;
and once I do know which ones they are, I won't know where they are;
I will need to use a feedback loop. crash must tell a hunt-it-down
script which modules are needed, then that script tells crash where
to load up the .ko files. Perfect. Thank you so much!!
