comment Difference between Login Shell and Non-Login Shell?
I think the question is better phrased as "Why do/should we care to differentiate login and non-login shells?" Many places on the web already tell us what are the differences, in terms of what startup files each read; but none of them seems to answer the "why" in a satisfactory and convincing way. Example use cases where you definitely do not want one or the other behaviour would be great.

comment What kind of bad things can happen if I disable APIC (not to be confused with ACPI)?
Using a newer kernel is not an option because the original one was customized by IBM or SuSE, and nobody among the stakeholders has the expertise to guarantee that patching on our own will work. What is it about the PCI USB 2.0 controller solution? Does it not rely on APIC somehow?

Actually, given udev, I wouldn't even have to find the corresponding ttyUSBx; I could just set a udev rule and assign the node name I want. But alas, udev only exists from SuSE 9 up (as far as the SuSE lineage is concerned).

comment How do I find out the device node corresponding to my device in SuSE 8?
I don't have access to the test machine right now. It's Friday night, well past office hour here in Hong Kong; and my client's office doesn't open on Saturday/Sunday. But assuming that it does have /proc/tty/driver/usbserial, what do I do with it? I have googled a bit about /proc/tty/driver/usbserial and it seems that it would contain some entries like: usbserinfo:1.0 driver:2.0 0: module:ftdi_sio name:"FTDI USB Serial Device" vendor:0403 product:6001 num_ports:1 port:1 path:usb-0000:00:1d.2-2 Which part of it is the x number (of ttyUSBx) that I want?
