_id utilities

_id utilities

[David Gómez]

Hi all,
A couple of questions. Why aren't "scsi_id", "cdrom_id", installedby default? If they're now the standard utilities to manage persistentdevice naming they should be installed with 'make install'.
And, why is the default path to install them /lib/udev? It's alsoharcoded in the source and it doesn't look good. It'd be better toinstall them in /sbin
cheers,

Well it's Linux, there is no "standard". :) It's up to the distro's todecide what to put in here. There are also no "standard" rules installedby udev until now.

All tools can be called by just using their name: RUN="firmware.sh", ifthey are in /lib/udev. The tools are not really useful outside of udevand intentionally don't show up on shell autocompletion (scsi_id has asymlink to /sbin for backwards compatibility).
In general the udev tools will not give you any information which is notalready available in /dev/disk/by-*/, so there is no real need to makethem public in /sbin and get the pain of keeping the interfaces stable.

Yes, i think that to no install any rules is logical, it's up toeach distro to choose what rules to install. But, are there alternativesapproaches in distributions to do persistent naming? If not, i finda sane default to install *_id utilities.

Yes, but because "/lib/udev" is hardcoded in the sources, which isquite ugly ;).

"/lib", according to the FHS standard, is for "essential sharedlibraries and kernel modules". IMHO to hide binaries in /libstandard directories is not good, they should be in sbin.

Not if they are not supposed to be run from the command line.
And they are not.
