Oracle 8.4 moved some files from their oraclelinux-release package to a new
package named redhat-release. This update makes sure to remove redhat-release
as well as the other packages during migration to avoid conflicts with
rocky-release.
After a RHEL conversion any attempt to run subscription-manager would result in
an error. this was due to the RedHat certs having been replaced on the system
during the migration. To fix this we now copy any subscription-manager certs to
a temporary directory and if they have been removed during the migration we copy
them back at the finish. This means that subscription-manager now won't stop
working after a migration from RHEL.
We previously removed color because (1) it was outputting the color codes to the
log file, which we do not want and (2) nobody could agree on what colors to use.
I've reintroduced color now fixing (1) by allowing for separate output to the
log file and the console and only sending the color codes to the console and (2)
well, I've changed the blue for info messages to cyan, hopefully everyone's
happy with that, but I'm open to suggestions on the info color.
There are now three more file descriptors for specialized output control, making a total of 5:
fd1 - This sends to stdout and to the log file.
fd2 - This sends to stderr and the log file.
fd3 - This just sends to stdout.
fd4 - This just sends to stderr.
fd5 - This just sends to the logfile.
There are also three additional functions:
msg_format - Intended to be used by infomsg and errmsg, this accepts a variable
name and one or more string args. If there is just one string after the
variable name then it is copied to the variable verbatim. If there is more than
one then it is taken to be a format specifier and additional args to be passed
to printf (output going to the variable).
infomsg - This will accept either a single arg which contains a verbatim string
or multiple format / args to be processed by printf. The output of this will be
sent to the log file and also color coded and sent to stdout.
errmsg - Like infomsg but it uses the error color and sends output to stderr
instead of stdout.
/etc/issue used to contain a nice ascii-art RockyLinux logo that we would output
when this script was finished, but it doesn't anymore so there is no longer any
value to outputting this file.
Clean up the rocky-tools root dir, the mirror script has it's own subdir too.
This makes rocky-tools scale better. As this breaks existing links, we should
do it as early as possible, before GA.
