I presume you have had to run on RAM, considering you removed all drives

Yes. Mass deployment using Clonezilla in an extremely heterogenous environment. I had to make sure the OS got installed on the correct SSD, and that it was always named sda, otherwise Clonezilla would shit itself. The solution is a hack held together by spit and my own stubbornness, but it works.

Broke: /dev/sd*
Woke: /dev/disk/by-id/*
Bespoke: finding the correct device’s SCSI host, detaching everything, then reattaching only the one host to make sure it’s always /dev/sda. (edit) In software. SATA devices also show up as SCSI hosts because they use the same kernel driver.

I’ve had to use all three methods. Fucking around in /sys feels like I’m wielding a power stolen from the gods.

Our business-critical internal software suite was written in Pascal as a temporary solution and has been unmaintained for almost 20 years. It transmits cleartext usernames and passwords as the URI components of GET requests. They also use a single decade-old Excel file to store vital statistics. A key part of the workflow involves an Excel file with a macro that processes an HTML document from the clipboard.

I offered them a better solution, which was rejected because the downtime and the minimal training would be more costly than working around the current issues.
