Here's a quick patch to:
1) Add an environment variable "SYSFS_PATH" that libsysfs will check
for when getting mount point before searching system's sysfs mount
point.
2) A quick fix to sysfs_get_link where the bug was.
I have tested this out with libsysfs and with udev. I couldn't test
with klibc because I haven't got the tree to build with klibc without
my changes either. I made the link but get an error finding
linux/linits.h. I will figure that out.
Please have a look at the patch. If it's agreeable, please test it. I
really want to add some generic path manipulation functions for the
sysfs_get_link error, rather than my patch's hack. But, I haven't had
time yet to do that. You really sounded like you needed this for
testing, so I'm sending it out to you. I should probably add a
function to set the env variable(?).
support subdirectory creation/removal for NAME="/devfs/is/crazy/video0"
create parent subdirs for device node if needed
remove subdirs when last node is removed
set uid/gid of node specified in udev.permissions
only numeric id's are supported cause we can't resolve with
klibc or libc before real /etc is mounted
I integrated udev with Fedora Core. The main piece is simply building
/udev on boot, since we don't have an initramfs yet. We should also
clear out /udev on shutdown, for /udev directories mounted on persistent
media.
The attached script goes in /etc/init.d
Then do "chkconfig --add udev"
And the rest is handled automatically. I made it for Fedora but it will
probably work, with little change, on any Linux system.
Right now it only does sysfs-based discovery of block and tty devices,
since those are the only types of devices I have on my system. There is
a TODO in the script where we would add the other device types.
Fixup path for kernel includes when building with klibc.
klibc expects the symlink klibc/linux to point to a relatively up
to date tree, use -Iklibc/linux/include to make linux/ and asm/
includes resolve properly, as these won't exist in the regular
klibc/klibc/include location.
OK, I fixed that bug you hinted at earlier in my previous
sleep_for_dev() patch. I am sure you fixed it, but here we go
nonetheless, just in case.
I actually changed it up a bit. It is probably faster to count down
from SECONDS_TO_WAIT_FOR_DEV than count up.
I also made the lone 'path' argument const, since it can be.
Some other misc. bits, too.
here a new patch for the man page:
o namdev.permissions added
o corrected a few typos
o corrected text for config line format.
owner, group mode are only in namedev.permissions
(don't know what i was dreaming, while i wrote this :))
