I've got a headless server running Gentoo that I went to upgrade today. Since udev-197 appears to be a high-risk update, I decided to mask it for a month or two while things settle down. If I mask ">=sys-fs/udev-197", I get the following when updating:

Code:
# emerge --pretend --deep --verbose --update --newuse --with-bdeps=y world
These are the packages that would be merged, in order:

Calculating dependencies... done!
...
[ebuild  N     ] sys-apps/makedev-3.23.1  USE="-build (-selinux)" 120 kB
...
[ebuild  N     ] sys-fs/static-dev-0.1  0 kB
...


I can't see anything preventing the system from upgrading to sys-fs/udev-171-r10 (an "emerge --ask '=sys-fs/udev-171-r10' doesn't complain about masked, keyworded, or blocking packages). If I eliminate the package.mask entry for udev entirely, emerge wants to upgrade me to udev-197. Any ideas?

Mask sys-fs/static-dev and check what happens next. You already know you do not want it, so why not mask it and force Portage to suggest some other option?

It's now suggesting I rebuild sys-apps/busybox with the "mdev" use-flag enabled. Masking that in turn gives:

Code:
 * Error: The above package list contains packages which cannot be

read the output, mask sys-fs/udev-init-scripts and >=sys-apps/kmod-kmod-12
this should prevert udev from upgrading and should suppress the other errors.

Did that, after fixing the obvious error in the kmod mask. New output:

Static /dev sounds like a feasible solution for a headless server, what's wrong with that?

It presumably requires a reboot, and like the udev-197 upgrade, carries a risk of the server not working after the reboot. Otherwise, I would -- I'm getting sick of fighting with udev.

Think clear now.
You do have device nodes for your devices. Created by udev. What stops you from keeping these nodes while removing udev? No reboot needed.

I don't know! Isn't this what sys-fs/static-dev is for? But I remember static dev ages, all nodes just were there. I'm sure with some precaution it is achievable. Also see http://bugs.gentoo.org/107875
If I was you I'd try it out on a test box.

are you sure you've masked udev-197?

add the -t flag to the emerge pretend and see what is trying to pull in what

It sounds like some dependency is needing either udev >= 197 or static dev
Find out what it is.

I've had to mask several newer packages to keep them from complaining about udev 197 being masked.

I moved to the new udev, and had a few problems, but I've gotten through them. Are you working harder to avoid the new udev than you would have to do adapt?

That said, I have not taken on the new network names. I think that change is going to get rolled back, right after Linus has a non-functional boot, and rips the udev developers a new one for breaking his system.

If the emerge output is to be believed, the offending package is GCC 4.6.3, which makes no sense whatsoever:

If I upgrade udev and something breaks, getting console access to this server requires two people and takes half an hour. Avoiding an extended wrestling match with a shelf full of computers is worth some effort.

Mask udev-init-scripts and see if that doesn't force an older udev to be used.

I have this in my portage.mask
Code:
>=sys-fs/udev-171-r7
>virtual/udev-171

as I'm quite happy with udev-171-r6 in my local portage tree.

Edit to add: also mask >sys-fs/udev-197

Already masked. That's what the '#' in the emerge output means.

as Anon-E-moose pointed out you need to mask >virtual/udev-171 too.
