$FTPUPDATES="rufus.w3.org/linux/redhat/updates/$RHversion/en/os"; |
|
} |
This file automates the usage of Martin Siegert's "check-rpms" |
} |
script. It runs through a list of possible mirror sites |
if (!$FTPSERVER) { |
until it finds one with a reasonably good FTP connection. |
print "Cannot find a working ftp server.\n"; |

} |
=head2 Future directions |
print "Using $FTPSERVER for ftp transaction...(please be patient)\n"; |
|
my @rpms=`perl loncom/build/check-rpms -ftp $FTPUPDATES`; |
Eventually, this script may have a simple argument format |
if (@rpms) { |
that allows the user to VIEW, DOWNLOAD, or AUTOUPDATE their |
my $rpm_count=scalar(@rpms); |
computer. Or, this script may evolve into an interactive |
print(<<END); |
series of steps: For example, there may be questions like this: |
**** WARNING **** You need to update at least $rpm_count RPMS shown in |
|
|
=over 4 |
|
|
|
=item * |
|
|
|
Do you want to (D)ownload or (A)utoupdate the RPMs |
|
in the list above? |
|
|
|
=item * |
|
|
|
Specify a download location for the RPMs |
|
(default=/tmp/update_my_rpms/)? |
|

|
Note that there are no current plans to automate a software upgrade of the |
|
kernel. This step should be performed by a qualified system administrator. |
