system halt on invalid udev.rule

system halt on invalid udev.rule

[Bob Barry]

Due to an editing blunder I left a line containing:
	NAME="ttyLT0", SYSLINK="modem"
near the top of my udev.rules.  At next startup, the system 
said that my root device (/dev/hda3) did not exist, and 
offered "retry or enter password for shell".  I would suggest
that udev be modified to cope more gracefully and informatively
to bad rules.  Something like samba's "testparm", but for udev
rules,  would be useful too.

You mean like "udevtest" which is in the udev release?  :)

thanks,

Dunno.  After making 021:

	udev-021> find . -type f | xargs grep -li udevtest
	./ChangeLog
	./udev.spec
	./Makefile
	./udevtest.o

There seems to be no doc, no man, and no builtin "usage"
for udevtest, and my distribution (Gentoo) does not install it.

To the user, it's inscrutable:
	udev-021> ./udevtest -h       
	udev-021> ./udevtest --help
	udev-021> ./udevtest -v
	udev-021> ./udevtest --version
	udev-021> ./udevtest
	udev-021> ./udevtest xyz                          
	udev-021>

I'll look at the code and see if I can figure out what it does.

Thanks,

Bob

Try:
	./udevtest /block/sda

if you want to test naming /block/sda

And yes, a manpage or help options might be nice to have :)

thanks,
