Looking to get up-to-speed on Fedora LiveCD so I can custom build my
own security tools that I can boot from cd, rather than lug around my
laptop everywhere. I did see the Security fedora livecd wiki, so
I'll have to poke around there as well.
I'm getting the following errors when booting the livecd iso that I
created in vmware.
- - - cut - - -
udevd[297]: add_to_rules: the 'device' link is deprecated and will be
removed from a future kernel, please fix it in
/etc/udev/rules.d/00-cdlabel.rules:1
--------------------------------------
WARNING: Cannot find root file system!
--------------------------------------
- - - cut - - -
if I add root=/dev/sr0 to the boot line, the cd boots fine, so I'm
curious as how to fix the udevd error.
I'm pretty sure this has nothing to do with the problem, but can
someone explain these hardcoded(?) numbers to me? This is about the
only thing in mayflower that I don't really understand-
(I.e. where can I go to find documentation on these sysfs types, so I
can feel convinced that these lists of numbers (0,7,14,,4,5) are
complete/correct)
I guess those numbers are generic peripheral device types as per ancient
X3T10 recommendation
Table xx - Peripheral device type

either as per SPC-3 clause 6.4.2 "Standard INQUIRY data"

that is pretty much the same for the types in question.

In the hope it helps.
Excellent. Thanks.
