There are modules that cannot be added directly into the site-packages directory to be recognised inside an AWS Lambda environment. When that happens, you have to get an Amazon Linux image from Docker repositories and make your own compiled environment in a container version that will run on AWS Lambda

For example, if you want to use Python 3.6 a good choice will be amazonlinux:2018.03 in case you want to install more packages e.g. pandas, numpy, scipy

How can I get a filesystem label from sysfs?

Asked 2020-Apr-22 at 13:26

How can I get the label of a filesystem using /sys? I know I can get much of the info about a block device by going to /sys/class/block/, e.g. /sys/class/block/sr1 for a cd that I know has the filesystem label config. I hunted through each item, found everything but the label.

I did dig through the lsblk source code, which, in turn, depends on calling udev_device_new_from_subsystem_sysname in libudev, so I went through that. It does appear to populate the property ID_FS_LABEL_ENC, but I cannot figure out where it takes it from in the tree, unless it is tracking it elsewhere?

I would just use libudev, but need to access outside of a C program.

...

ANSWER

Answered 2020-Apr-22 at 13:26

I think that the problem here is that you seem to think that the label of a volume is a kernel thing, as is the size or the free space.

But AFAIK it is not, the kernel doesn't care at all about volume labels, it is just a thing that goes from the in-disk format to user-land: there is no kernel API to get that information. If you need it, you just open the raw binary volume and read the data from there.

But then, there is the big issue that every filesystem is different, so you need special code to manage every single partition type there is. Fortunately, somebody has done the hard work, and you have blkid, part of util-linux available in most Linux distributions. If you need it, you can call the program directly, or link to the library libblkid that does the hard work.

Naturally, to use blkid/libblkid you need read access to the block device, that is, root access. If you think that root access should not be needed to read a label, the people from udev think the same, and that is why there is a udev rule that copies the label when the filesystem is first dectected (running blkid of course). This is the ID_FS_LABEL_ENC you already know about.
