    2 yum questions

    1. What does the output from yum mean.

    2. How to use the variables that the man page talks about in the server section?

    Yum screen messages

    I'm, reasonably new to Yum, but the general gyst as I see it is yum maintains a list of headers of applications on the system, and downloads updates in three categories
    core 100% |=========================| 1.1 kB 00:03
    updates 100% |=========================| 1.2 kB 00:00
    extras 100% |=========================| 1.1 kB 00:00

    Yum then compares your requested update, say, with dependencies it knows about from the headers

    ---> Package ghostscript.i386 0:8.15.2-1.1 set to be updated
    --> Running transaction check
    --> Processing Dependency: for package: ghostscript

    If Yum finds an application dependent upon some part of what you have asked it to replace it then cascades the dependency check through that application also

    --> Processing Dependency: for package: kdebase
    --> Processing Dependency: for package: cyrus-sasl-md5
    --> Processing Dependency: for package: wget

    This often results in more headers being downloaded, in order to resolve these cascaded dependencies

    ---> Downloading header for kdebase to pack into transaction set.
    kdebase-3.5.3-0.4.fc5.i38 100% |=========================| 544 kB 00:13
    ---> Package kdebase.i386 6:3.5.3-0.4.fc5 set to be updated
    ---> Downloading header for cyrus-sasl to pack into transaction set.
    cyrus-sasl-2.1.21-10.i386 100% |=========================| 17 kB 00:00
    ---> Package cyrus-sasl.i386 0:2.1.21-10 set to be updated
    ---> Downloading header for wget to pack into transaction set.
    wget-1.10.2-3.2.1.i386.rp 100% |=========================| 17 kB 00:00
    ---> Package wget.i386 0:1.10.2-3.2.1 set to be updated

    This may continue for a considerable length of time after which Yum will tell you how much and what it proposes to download, and you say 'yes' or 'no'. On occasion it cannot resolve the dependencies and bums out and it was all for nothing!

    Error: Missing Dependency: is needed by package iiimf-libs
    Error: Missing Dependency: iiimf-libs = 1:12.2-4 is needed by package iiimf-libs-devel

    Now a third Yum question

    I hope that a Yum knowbie is around to answer this one:
    My response to '4o4 ... 2 questions ...' was real experience. All I wanted to do was update ghostscript, and after > an hour downloading >30MB of headers Yum decided to bum out on a missing dependency for a different application. I have no immediate interest in updating the 100 or so other applications that were on Yum's 'mind'. Is it not possible to have the new ghostcript along side the other dependencies, thus not disturbing the cascade of interdependent application? Can Yum do this or is it necesarily a manual job?
