This is an update from "Uncoloring ls" which documents how to disable colored ls output on older systems which define that behavior in a profile.d script.

Uh oh, Active Directory password is going to expire!
Ugh, do I need to log into a Windows workstation to change by password?
Nope, it is as easy as:

I needed to prepare some SD cards for deployment to Android phones. After formatting the first SD card in a phone I moved it to my laptop and was met with the "Error mounting... unknown filesystem type exfat" error. That was somewhat startling as GVFS gracefully handles almost anything you throw at it. Following this I dropped down to the CLI to inspect how the SD card was formatted.

Finally got around to updating my work-a-day laptop to openSUSE 42.3. As usual I did an in-place distribution update via zypper. This involves replacing the previous version repositories with the current version repositories - and then performing a dup. And as usual the process was quick and flawless. After a reboot everything just-works and I go back to doing useful things.

Occasionally one gets reminded of something old.
[root@NAS04256 ~]# kinit adam@example.com
Password for adam@Example.Com:
kinit: KDC reply did not match expectations while getting initial credentials
Huh.
[root@NAS04256 ~]# kinit adam@EXAMPLE.COM
Password for adam@EXAMPLE.COM:
[root@NAS04256 ~]#
In some cases the case of the realm name matters.

Almost every server I work with is a virtual machine; accordingly I like to do one small install with all the packages that I always want [like pam-nss-ldapd, snmp-utils, dstat, etc...] but don't install by default. Then I make sure VMware tools is installed and operational. From that point forward I can just clone that one VM and add to it when I want a new instance of something.

Attempting to create a file on a large XFS filesystem - and it fails with an exception indicating insufficient space! There is available blocks - df says so. HUh? While, unlike traditional UNIX filesystems, XFS doesn't suffer from the boring old issue of "inode exhaustion" it does have inode limits - based on a percentage of the filesystem size.

Which application manages this type of file? How can I, by default, open files of type X with application Y? These questions float around in GNOME forums and mailing lists on a regular basis.
The answer is: gvfs-mime .

It is common knowledge that on CentOS/RHEL hosts you can enable and disable defined reposities with the yum-config-manager. However it is also possible to use yum-config-manager tool to set any repository parameter using the setopt parameter.

dd is an underrated tool. What it lacks in user interface it makes up for with its swiss-army-knife number of purposes; from testing, to secure wiping, to backup and restore. But that user interface... it is bleak.
