Nice, thanks a lot. I had both issues (error messages while booting) on 32bit and 64bit -current. Your latest builds of eudev and udisks fixed them.

I had to install the latest aaa_elflibs as stated by bormant. My system kept hanging up at boot with hald.
I also got many errors during the boot.
Following the instructions cleared my problem.

current 64 vbox vm, removepkg udev, slackpkg update, ..install-new, ..upgrade-all, nothing unusual, no odd messages

rebooted, mkinitrd, rebooted

ran some usual apps, everything's working fine

Did you need to do anything with the aaa elflibs?

glorsplitz · 11-20-2015, 10:21 PM

@pzognar, no, kernel... and aaa_elflibs are commented in blacklist.

Code:

Failure writing database //etc/udev/hwdb.bin: Bad file descriptor

This is solved with the latest build, thanks. Some mirrors did not sync yet, but it's up on kernel.org

Made the same mistake as kikinovak here - just did slackpkg upgrade-all stuff without thinking it through or reading the instructions in changelog. Result was a boot but with non-working network manager and X which were both trying to use udev.

However once I understood what was going on, I was able to manually install the eudev and libgudev packages, remove udev and got all the basics working.

Some other stuff being re-built from slackbuilds now, but that's expected of course.

Looking into it now.

Slackware-current 32-bit full install,
updated from http://slackware.osuosl.org/slackware-current,
last record in ChangeLog.txt made on Fri Nov 20 21:52:15 UTC 2015.

As I can see, there are 105 binaries in 26 packages that still linked with libudev.so.0 (from old udev package, now from aaa_elflibs), the list is attached to this message.

did you use ldd ?
it returns all the libraries needed to run something, not just the ones the binary is linked against

instead use
readelf -d binary/library | grep NEEDED

bormant · 11-21-2015, 06:29 AM

genss,
No, this is "readelf -d" results.

genss · 11-21-2015, 06:49 AM

nice
it's just that a couple of them looked weird (like imagemagic and xfce-panel things)

Smokey_justme · 11-21-2015, 06:53 AM

I have to say, since I didn't upgrade the aaa_elflibs package (I understand the need for the package but I don't like updating it), I did had to symlink libudev.so.0 to libudev.so (which is a symlink to libudev.1.6.3) in order to use Xfce (xfce-session was throwing an error about the file and couldn't start)... Everything seems to work fine for now..

Hi!
I had an issue with OpenVPN after the upgrade.

Code:

ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)
Exiting due to fatal error

After creating the device node, OpenVPN was working again as expected.
Thanks for looking.

The upgrade went smooth. I first removed udev, then upgraded aaa_elflibs. This resulted in gpg not working anymore, so I simply installed eudev and libgudev by hand using installpkg. Then I upgraded the rest. So far my system booted fine and is in a usable state.

One thing I noticed: my hard drives no longer show up in /dev/disk/by-id, only my USB SD card reader's slots are shown there. Is there anything I missed doing?

edit: my partitions do show up in /dev/disk/by-uuid, though.

Hi lems. All my drives are shown both in /dev/disk/by-id and /dev/disk/by-uuid. I removed udev first, installed eudev and libgudev, then did an upgrade-all for the remaining stuff, including the latest aaa_elflibs rebuild.
