[gentoo-user] another old server: what about udev and CONFIG_DEVTMPFS ?

[Stefan G. Weichinger]

Another > 5 yr server that needs some care.

sys-fs/udev-151-r4 and a kernel without CONFIG_DEVTMPFS set.

The old udev blocks openrc etc etc ...

Aside from: "install from scratch" ->

what happens if I upgrade udev before booting a kernel with
CONFIG_DEVTMPFS set?

Problems?

I'd like to upgrade udev, then install openrc etc ... before I can drive
there and reboot the box.

Yes, it won't work. And the ebuild will error out.

You intend to drive there anyway and reboot it. Rebuilding udev & openrc
will probably take 15 minutes.

It's such a little time, why are you trying to save 15 minutes in
advance by taking an unknown and risky path? Just do everything on-site,
it's safest

~ 90 min drive one way ;-)

Thanks anyway, Stefan

I could install openrc with USE="-netifrc" now ... then it doesn't pull
in netifrc which depends on udev etc etc

Not a real solution as now I miss net.lo  ... oh my.

I scp'ed it over ;) just to make that one reboot work ...

I've had a few of those myself :-)

I always figured if I was in for a 4 hour minimum trip anyway, I really
owe it to the customer to spend an extra 30 minutes to be 100% sure
everything was done correctly.

Um... what? The ebuild will display a warning, but it does not die.

The "customer" in case tells me that he has no money and that I
shouldn't invest too much "time"

The initial trigger for all the current "investigation" is a dropped hdd
from the raid arrays ....

The guy opted out of being a real customer in late 2010 or so .. and now
mdadm emails me.

Don't ask how the backup reports look.
